Would you care to share the last time you stuck your foot in your mouth and had a real good chew?

Mine was this. I had just started working for a transport company driving between terminals. I was at one of our other terminals when I saw another driver that was a woman. Not what you would call a looker. Anyway, a few days later one of the guys was asking me how I liked the job so far. I said it was alright and making small talk as another driver came up to us. I then commented on this woman driver described her and then kept yakking about how unattractive she was. The second driver left us without a word. The first driver had this huge smile on his face and told me I should stay away from that guy for awhile. When I asked why he told me that that was the other guys girlfriend. Talk about feeling stupid.
