How about the popular bumper sticker from the early ‘90’s;
“God....Please let there be another Oil Boom, I promise not to piss it away this time.....(I always loved that one)
I remember as a child he had a gang truck.
One of the hired hands from the university (future engineers) had attached a bumper sticker about being a piano player.
Dad at the end of Summer would give all the young college kids a coffee mug that said “I'm so smart I make myself sick”.
Nothing like running a long handled Mexican backhoe squaring up ditches to help make a young kid decide to stay in college and get an education.
