Heard about this from a guy I knew years ago:

It's Friday and they both get paid, then cash their checks.  They go on a two day bender, never going home.  On Sunday afternoon, they drive to one guy's house to drop him off.  The guy insists they both go in the house - the guy's wife may not be in a good mood.

The wife confronts her drunk husband.  "Where have you been?  Where's your paycheck?"  After several minutes of this, the guy finally says, "Beulah, what the hell do you need money for?  You don't drink, don't smoke, and you got your own pussy!"
