A WWII veteran earned his High School diploma at 91, 74 years after dropping out. When asked what happens next, he said 'College Girls'.

At a party an older couple is talking to a young one. The young man says to the old man, “I’ve heard that when you get on in years, you can’t have sex anymore.”
“I don’t know where you heard that, young man, but we have sex almost every night,” the older gent replies. “Really?” “Sure. Almost Monday, almost Tuesday, almost Wednesday….”

An elderly man goes into a brothel and tells the madam he would like a young girl for the night. The surprised madam looks at the ancient man and asks: How old are you? “I’m 90 years old,” he says. “90!” replies the woman. “Don’t you realize you’ve had it?”
“Oh, sorry,” says the old man. “How much do I owe you?”

Two young businessmen in Florida were sitting down for a break in
their soon-to-be new store in the shopping mall. As yet, the store
wasn't ready, with only a few shelves and display racks set up. One
said to the other, "I'll bet that any minute now some senior is going
to walk by, put his face to the window, and ask what we're selling."
Sure enough, just a moment later, a curious senior gentleman walked up to the window, looked around intensely and rapped on the glass, then in a loud voice asked, "What are you sellin' here?"
One of the men replied sarcastically, "We're selling ass-holes."
Without skipping a beat, the old timer said, "You're doing well. Only two left."
Seniors -- don't mess with them, they've been around!
