Grandma's Condition

Q: What's that wrinkly thing on Grandma?
A: Grandpa.

Old Math Professor

A college math professor and his wife are both 60 years old. One evening the wife comes home and finds a note from her husband. It says: "My dear, now that you are 60 years old, there are some things you no longer do for me. I am at the Holiday Inn with my 20-year-old student. Don't bother waiting up for me." He returns home late that night to find a note from his wife: "You, my dear, are also 60 years old and there are also things I need that you're not giving me. So, I am at the Motel 6 with one of your 20-year-old students. Being a math professor, I'm sure you know that 20 goes into 60 way more than 60 goes into 20. So, don't YOU wait up for ME."

Memories

An old man is sitting on the park bench crying. Another old man sits down next to him and says, "Hey buddy, what's the problem?"
The old man wipes the tears from his eyes and explains, "I've got this beautiful, 35 year old wife, and all she wants to do is make love from the moment I walk in the door till the moment we go to sleep and then when we wake up again."
"So, what the hell is the problem?"
"You don't understand... I forgot where I live!"
