I thought my joke about pants-free cell phones being safer while driving was easier to get than it is.
I somehow became the designated writer of quips and quotes on the chalkboard at my favorite bar. I wrote my pants-free phone gag on the chalkboard, and I found out a few days later that nobody got it. One of the bartenders asked everyone in the bar to explain it to her, and no one could. 
So, I’m gonna take it off my sig, and replace it with, uh, probably something just as lame.
