Sometimes I do things solely because they'll be funny later, and most times I'm the target audience.  For example, when the check is brought to the table at a restaurant, it usually includes a copy for the merchant as well as one for the customer, and sometimes there's a place to sign on the customer's copy, which is odd because I as the customer have no need to see whether I signed it or not.  Since it doesn't matter either way, I sign it, though I use an unusual pseudonym, usually something along the lines of Poopy Pants or Pukey Jerkface.  Then later when I'm going over my finances, I'll find the receipt and have a good laugh. #psychology
