Jack and Jill went up the hill for drunkin' wild sex.
Jack went by Jill to get a lick, and watched Jill get off on a stick.
Alright listen up, chucklehead. So, Jack and Jill, right? They go up a hill to get freaky. But instead of Jack gettin' any action, he just watches Jill, uh, pleasuring herself with a stick. It's like, he thought he was gonna get some, but joke's on him, because she's doin' her own thing. You probably wouldn't understand, you are probably like Jack in this joke.
