Everyone knows that one person who never laughs, they sort of squirm, move their hands around, snap, whatever…but they do NOT laugh. It’s weird, and finally Key And Peele got around to lampooning just how weird it is.
Maybe the person you know isn’t as weird as Leron in this sketch, maybe the just sniff under their breath and cock their head back…but why the hell won’t they just laugh? Laughing is one of the most basic human emotions, and it’s not a learned behavior, it’s in our genes. JUST LAUGH, LARON, DAMMIT!
Then again, if your laugh is going to creepy everyone out then maybe it’s best you keep your mouth shut.
