Amnesia Medication Theft

Alright listen up, buttercup. So, this dummy steals his pal's medicine for forgetfulness, right? And the friend gets mad. But here's the kicker: the thief tells him to "forgive and forget," which is, like, the perfect thing to say to someone who can't remember stuff anyway. It's funny because the friend is so dense, they don't realize they're being played like a cheap kazoo. You probably still don't get it because you're a dum-dum.
