From the geography teacher, Mr. Poop:
7th Grade Student: Mr. Poop, how did a turtle paint the Sistine Chapel?
7th Grade Student: They said he had to lay on his back to paint it. That kills a turtle.
Mr. Poop: No it doesn't and a turtle didn't paint the Sistine Chapel. It was Michelangelo.
7th Grade Student: Well why did his parents name him after a Ninja Turtle?
