Some more geezer humor that people have shared with me:
Snow is like old age sex. You don’t know when it will happen or how long it will last.
Definition of ROMEO: retired older men eating out.
A young man was teamed with a geezer in a golf game. On one hole the young man's ball ended up behind a tall tree. The geezer said, “When I was your age I hit a ball from this same spot over that tree.” Not be outdone, the young man tried the shot, and it hit the tree and bounced back to where it started. When the young man expressed displeasure at the geezer’s comment, the geezer added, “When I was your age the tree was only three feet tall.”
