FISHING
A teenage boy and his grandfather were fishing one day. While fishing, the old man starts talking about how times have changed. The boy acknowledges this and starts talking about the various problems and diseases going around today.
The teen says, "Gramps, they didn't have a whole lot of problems with too many kids when you were young did they?"
The grandfather replies, "Nope."
The teen says, "Well, what did you guys use for birth control?"
The old guy replies, "A wedding ring."
