Way back when Noah was on his ark and tending his animals, he noticed the other animals were mating and bearing eggs and other young...except for the snakes. He pondered this looking out his ark window and he happened to see a hollowed out tree floating by. Struck by inspiration he got Shem and Ham to open the ark door and he dragged the tree inside and threw the snakes inside in, because, as everyone knows "in logs adders multiply"...
Many moons ago I used to teach Math. These math jokes were my favs:
Q: What do you get if you divide the cirucmference of a jack-o-lantern by its diameter?
A: Pumpkin Pi!
Q: Why do you rarely find mathematicians spending time at the beach?
A: Because they have sine and cosine to get a tan and don't need the sun!
"Students nowadays are so clueless", the math professor complains to a colleague. "Yesterday, a student came to my office hours and wanted to know if General Calculus was a Roman war hero..."
And here's one I couldn't tell in class:
"What happened to your girlfriend, that really cute math student?"
"She no longer is my girlfriend. I caught her cheating on me."
"I don't believe that she cheated on you!"
"Well, a couple of nights ago I called her on the phone, and she told me that she was in bed wrestling with three unknowns..."
Woody Allen jokes, "I took all the abstract philosophy courses in college, like 'Truth And Beauty', 'Advanced Truth and Beauty', 'Intermediate Truth', 'Introduction to God', 'Death 101'."
