Tom and Bill are married to twin sisters. TOM: Hey, Bill- If I had sex with your wife would that make us related? BILL: Nope. . . but it would make us even! Jerry and Bob are two older gentlemen: JERRY: You know, sex with the old lady just isn't the same any more. BOB: Whaddya mean Jerry? JERRY: Well, the old girl is gettin' so loose down there that I can barely feel it when I stick it in her. BOB: Well, did you ever think about turnin' her over and using the other hole? JERRY: WHAT!!?? And get her pregnant?! No way!! BOB: I traded in the old lady for an outhouse the other day. JERRY: Why the hell would you go and do somethin' like that? BOB: Well, the hole was smaller and it smelt better. What has 4 legs and eats ants? . . . . . My two Uncles!!
