Fitness Birthday Puns

So we were out celebrating my dad’s birthday last night. I said, “You and Mom are healthy and look good for your age. I wish I had your genes!” (I’m adopted.) Without missing a beat, Dad said, “You can have mine if you want, I can barely fit in them anymore!”

For the past three years I've held scavenger hunts to celebrate my birthday. This year I've decided on the theme, "Dads' Night Out." Examples of items on last year's (non-dad-themed) list: "Play red light/green light with at least three strangers," "Switch pants with a stranger," and "Haiku written by a bartender." All items require physical, photographic or video evidence. What are your ideas for dad-themed items or jokes I can fit in here and there? Any other ideas on how I can make this year the best year yet would be appreciated.
