If you wear headphones while you work, remember this one thing when you try to hold back a fart: Just because you didn't hear it, does not mean everyone else didn't hear it.
This weekend I was helping my dad with a project. We made a trip to Home Depot to get a tube of epoxy adhesive. Before going to the checkout lane, my dad decided he needed to visit the restroom.
This is what NOT to say to your dad in this situation: “Do you need me to hold your caulk while you pee?”
