So my dad and I went to a baseball game and during the game he turns and asks, "Son, how many people do you think can fit in this stadium?" When I began to think about it, he gave me this look and then cheekily says, "I just want a ballpark estimate".
He thinks this is his magnum opus dad joke.
Me and this girl I'm seeing were walking around the mall and we decided to go to Hot Topic to kill time. Walking around we saw some car fresheners with band logos on them and my gf picks one up and says "hmm I wonder what Nirvana smells like?"
Without hesitation I answer "Teen Spirit"
It was the most perfect joke set up ever and I don't think I'll ever top it. It was my magnum opus. I don't think she appreciated it as much as I did.
