Global warming, my foot!

My hot, sweaty foot, that is. Or, feet. How is it that it's only 7:30, and my feet are already sweating?! (At least I just had a shower a half-hour ago, so they don't smell. Yet.) Oy. Yesterday the thermometer outside my classroom read 27 degrees. With the air conditioning on. Maybe I need to find a clothing-optional school to work at for the summer, if it's already this hot!
