That's my line Eric. I also tell them it proves that I'm more in touch with my feminine side (that's actually a bit of visual humor, I'm huge and ugly as a rock).
I like it and could use it. In my own case, I was on the swim team during high school. As the season wore on the idea came up of shaving down for meets. I looked at them and said "not a chance in hell". Probably would have shaved a second or more off my time though.
