Why did Al Qaeda fail geometry?
'Cause they ruined the Pentagon.
Why is the Pentagon mad?
Because it didn't get two pizzas, but only one plane pizza.
You know why the Twin Towers were more remembered? A hexagon is more commendable than a pentagon.
I was in math class, and we were learning geometry. My teacher said, "PENTAGON!" then all of a sudden, PENALDO burst into the room! He thought we were talking about PENS, so he came looking for some because he's a finished pen merchant! Shame on you, Penaldo, for ruining my education! 🤬
There was a math teacher on a plane that crashed. What was the last thing that went through their head?
A pentagon!
