(Dad) I just got an invitation to my thirty year High School class reunion. I don’t think I’m going to attend.
(Son) Dad isn’t it true that each year the graduating class is larger than the year before.
(Dad) Yes, that’s generally how it works. By the time you graduate son the graduation class should be double of what it was last year.
(Son) My point exactly, based on that I really think you should attend.
(Dad) What point?
(Son) I just did the math in my head and it just wouldn’t be fair to the other two graduates if you missed it.
Joe: When I would wear my hand-me-downs to school, all the boys would make fun of me.
Moe: What did you do?
Joe: I hit them over the head with my purse.
Granddaughter: It’s March 14th grandpa, national “pi” day.
Grandpa: I love pie!
Granddaughter: Not that kind of pie grandpa, I’m talking about a formula!
Grandpa: Back in my day we called it a recipe!
Granddaughter: Graaaand Paaaa, not that, it’s a mathematical formula, you know an equation.
Grandpa: That’s the problem these days, everyone makes things so complicated. In my day we used things like cups, teaspoons and tablespoons. We didn’t need math if we wanted to bake a pie.
Granddaughter: Oh, I see your point! So what would you like, apple or cherry pie?
Grandpa: Finally, a young person who actually understand things.
Grandpa: I can't find the send button on my cell phone.
Granddaughter: I see the problem grandpa, you're using a calculator.
Grandpa: It's always a calculated risk doing things without my reading glasses.
Granddaughter: No wonder things didn't add up.
Grandpa: Very "Punny" young lady, you're as bad as I am!
Granddaughter: And exactly how did you arrive at that equation?
Grandpa: Time for my nap, I rest my case!
