This is not so much a request for a description or a link or a retelling. It is a request for you to try to remember the very funniest thing you can, and to associate that funniest thing with the person you think was responsible for it.
It could have been a joke, a gag, a bit, some pratfall, one of those America’s Funniest Videos, something on YouTube, somthing in a cartoon. No limits.
Just when you see the words “funniest thing ever” what do you think of? And who made it funny?
In my case, I think I laughed hardest and longest at Lee Evans in Funny Bones (1995). If you’ve seen that movie and not found it outrageously funny, I’d like to know about why. And if you haven’t seen it, I can recommend it for Lee’s bits alone. Other parts are amusing to funny. Lee Evans is side-splittingly hilarious.
