"Settle Down" joke

I'd graduated from college and moved back home. I spent my days sleeping and my nights were all spent with my buddies out chasing girls and partying. In short, I was just taking it easy and didn't have any specific goals in mind.

My grandfather stopped by and asked what my plans were.

"Well, Grandpa, I thought I'd just take it easy for awhile."

"Son, I think it's time for you to settle down and start looking for a job. Before you know it, you're going to be 30."

"But, Grandpa, I'm closer to 20 than 30. I've still got eight years before I'm 30!"

"Yes, but when are you going to be 20 again?"
