Dad Joke

Saw a man standing on one leg at an
ATM.

Confused, I asked him what he was doing...
He said: "Just checking my balance."

HahaHe better watch out for his arm - it's already cost him a leg!
HahaMy biology report titled: "Your Intestines: How Digestion Works" was marked down a grade. Turns out I had missed the colon.
My class essay on internal organs was too short, so I added an appendix.
