I work out regularly at the gym, and every so often - aka every other week - I either forget something or do something that makes me cringe and then go tweet about it. Here's a sampling:

Colorful socks. Last night I showed up at the gym to go running only to pull down my pants (don't worry, I was wearing shorts beneath!) and see I forgot to change my socks. Oh, I was in socks, but they were pink argyle socks. Thin, too. Not the worst thing that can happen, but like . . . I wasn't trying to make a statement on the treadmill catwalk. Or get a blister on my heel.
