To be fair, I don't even know why I bother to try and make my signature resemble what it's supposed to say whenever I sign on an screen, it's already becoming bad enough on paper I should just give up on screens. Especially when the styluses are fatter than crayons I used as a kid.
Also, it reminds me of that old thing on the internet where the guy was signing different things ("THIS CARD WAS STOLEN", drawing pictures, etc.) for credit card swipes to see if anything would ever happen.
