I know what makes me laugh is when there’s a disconnect between what is expected and what actually happens.
As a sketch writer, I’ve found that there are two modes of how to get to the funny: the “normal” character in a crazy situation and the “crazy” character in a normal situation.
They say comedy = tragedy + time, but it can’t be humongous social tragedy until at least a few hundred years have passed. OTOH, there’s the dumb guy in a wheelchair who couldn’t accept that he missed the elevator, bashed open the doors with his chair and the fell down the shaft and died, well, that was just one Darwin Award winner who got what was coming to him, so that’s funny. Sick, but funny. What happens in real life that’s funny to me is when I do (or someone else does) something embarrassing that, in retrospect, we know made us look silly and could’ve cause (and sometimes did cause) social opprobrium.
If everyone more or less agrees on what’s socially appropriate, any exaggeration of that, for good or bad, can be funny. There’s a reason why this is one of Eddie Murphy’s most famous bits of comedy.
