so a couple of years back, my co-parent played an april fool joke on her wife by putting a leek (the vegetable) in the bath, and then going downstairs and saying "oh no, I think there's a leak in the bath" to her wife so she'd come look at it & see the vegetable and laugh etc

so this year her wife was like "hey kid, what should we do to play a joke on mummy this year" and he thought about it for a moment and then said "we should put a cucumber in the bath, and then say 'mummy, the bath is a bit cucumbery'"

perfect april fool joke imo, 10/10 no notes

although my favourite is still the first year he learned what "april fools" was (he was... three, I think?), and "pranked" everybody by spending the day pointing to various non-stegosaurus objects and announcing "that's a stegosaurus!"
