When blonde jokes were really popular dad would call me and say "Hey I got a joke for ya, but don't tell Beth"
I would wait till I got off the phone to tel her.
Later on dad would call with the same routine and I would tel Beth the joke while I was still on the phone with dad.
This eventually turned into "Hey put Beth on the phone I got a joke for her"
The best part is she doesn't remember them so you can tell her the same jokes every six weeks. It's almost like there is a joke in there as well.
