Can someone explain this to me? I only know this guy from that Simpsons episode where Homer imagined (?) this Ray guy who helped Homer fix a roof or something

Yes, Homer might have been trying to fix a hole in his roof, then possibly met and befriended a roofer named Ray Magini, which is almost certainly an anagram for “Imaginary.” (Homer’s brain was theorized to be a genius because it turned out Ray might or might not have been imaginary!)

Also, I may have wasted my childhood and early adult years.
