Dad Joke
A joke so bad it makes you want to punch the person who told it. Usually comes out during speeches when no one is looking.
At a wedding, the dad says, 'Love is like a pizza... it's always good.' The bride looks like she wants to cry.
At a 18th birthday party, the dad says, 'You're not old, you're just a little mature.' The kid looks like he's about to die.
At a 21st birthday, the dad says, 'Wine is the only thing that will help you forget this day.' The guests all agree.
