There once was an X from place B
Who satisfied predicate P
The X did thing A
In a specified way
Resulting in circumstance C.
I still have no idea who originally wrote this.
I went out on a nice 90K bike ride and I had to stop halfway through and disallow Tusky from sending notifications about this toot to my Garmin

@rgarner

I read all the way to the end,
and was not disappointed.

@rgarner

There once was a [person] from [place]
Whose [body part] was [special case].
When [event] would occur,
It would cause [him or her]
To violate [law of time/space]!

@matildalove @rgarner We've clearly read the same bash.org thread...

It's always a marvel to me,
For a pendulum hanging quite free,
Each tick and each tock of a grandfather clock
Is 2Pi(sqrt(L/g)).

I still mention this to students at that level (even though it's an approximation).

A mosquito was heard to exclaim,
"A chemist has poisoned my brain!"
The cause of its sorrow
Was paradichloro-
Diphenyltrichloroethane

[EDIT: Corrected bracketing on 2Pi(sqrt(L/g)), thanks Anton]

@_thegeoff @matildalove @rgarner Here is a classic my mom taught me.

Johnny was a chemist, but Johnny is no more,
for what he thought was H2O was H2SO4!

There once was a lady named Fisk,
Who's fencing was exceedingly brisk.
So swift was her action
Lorentz contraction
Reduced her Rapier to a disc

(This was on the wall of my high school physics lab in the 80s, a teacher who was there at the time, and a colleague today, retires next month.)

Another variant (unattributed in my source):

A fencing instructor named Fisk
In duels was terribly brisk.
So fast was his action,
The Fitzgerald contraction
Foreshortened his foil to a disk.

The next one (also unattributed):

A rocket explorer named Wright
Once travelled much faster than light.
He set out one day
In a relative way,
And returned on the previous night.

I archived the top 50(?) or so on limerickdb before it was lost.

I think my fave is

A woman in liquor production
Owns a still of exquisite construction
The alcohol boils
Through magnetic coils
She says that it’s β€œproof by induction”

@knack @_thegeoff @matildalove @rgarner
There once was a pirate named Bates,
Who was practicing fencing on skates
When he fell on his cutlass,
Which rendered him nutless
And practically useless on dates.

@_thegeoff

Wait, I think g needs to be under the square root too...

@_thegeoff @matildalove @rgarner I think I remember the approximation comes from tan(x) is small for small angles?

@donlamb_1 @_thegeoff @matildalove @rgarner

Here you go @donlamb_1 -

The math I'm afraid is in tangles
It's tough for us mortals to wrangle
But here where the angle is small
We can use the approximate law
That tan(x) is x for small angles

@aadmaa2 @donlamb_1 @_thegeoff @matildalove @rgarner

If your need for precision is keen
It is quite readily seen
That it takes the direction
Of a proportional correction
By squared theta divided by sixteen

@matildalove @rgarner I had to make myself hear how it sounded; first read I didn't realize it was a legit limerick (but it wasn't on a thread of them, eitehr).

@rgarner a few meta-limericks I enjoy but can't credit either:

There once was a girl named Sue
Whose limericks stopped at line two

There once was a man named Dunn

And lastly, the one about Nero

@jrm @rgarner

There was a young man from Japan
Who wrote verse that never would scan.
When they said "But the thing
Doesn't go with a swing,"
He said "Yes, but I always like to get as many syllables into the last line as I possibly can."

@jonberger @jrm @rgarner
Oh that's interesting, it's a variant of the version I know, which goes like this:

There was a young man from Japan
Whose poetry never would scan
When told this was so,
He answered, "I know,
But I always try to fit as many words into the last line as I possibly can."

@rgarner

Welp, that's it. Limericks are now mathematically solved. Everybody go home; we're done here.

@argv_minus_one @rgarner Au contraire! Now we have an algebra of limericks, we still need to find "x", solving for all variables

@argv_minus_one @rgarner Speaking of mathematical limericks...

Integral of t-squared dt
from 1 to the cube root of 3
multiplied by cosine
of three pi over 9
equals log of the cube root of e.

@rgarner
I've been to Limerick
Twice or thrice
The Tesco was nice.

Am I doing it right?

@rgarner that’s great. The free limerick.

@rgarner

There once was a charming young miss
Who went down to the river to read.
A man in a punt
Stuck his hand in her eye,
And now when she reads she needs glasses.

@rgarner There once was a dev from Milan
Who deployed with no rollback plan
He pushed it at night
Then screamed at the site
And blamed it on poor old Nginx
@rgarner
There once was a lady from Hyde
Who ate sour green apples and died.
The lady lamented,
The apples fermented
Into cider inside her inside.
@rgarner
There is a lady at my weekly writing group who specializes in limericks. I'm sure she will love these
@screwturn @rgarner not a limerick but I saw this once: roses are red, violets are blue, some poems rhyme, but this one doesn't.
