Percentage Point Puns

This is more dad humor than a dad joke.

Cake day is coming up and so my son decided to give me a hard time about being old.

I responded that I may be old be he was catching up. He looked at me funny so I explained.

“When I was 24 you turned 1 year old. At that moment I was 24:1 or 24 times your age.

I am now 40 and you are 17 so 40:17 or 2.35 times your age. 24 is much larger than 2.35 so clearly you are catching up”

He responded, you can’t use ratios to compare two dates.

I said sure I can and made a graph:

I even included percentages to drive home the point.

He smacked his head and walked away.
