My twitter entry (in jest): ‘Wanting to foray into politics, thinking about selling a seat on the Metro-Urban Fellowship Leadership Committee to the highest bidder.’

A random co-worker (later, by the water cooler): “Haha, I saw your twitter entry! That’s so hilarious!”

Me: “Try telling that to the boss. He made me Twit-back. Jerk!”
