Mower's Crack?

Is there such a thing? If there is I was mighty close to it today. I mowed the lawn while Drew was at school. I kept bending over so I could dump the grass in the bin then clip it back to the mower. Little did I know that my sweat pants that don't fit right (because of my growing belly) started falling down. When I noticed that my underwear was showing, I quickly hiked up my pants and looked around the neighborhood to see if anyone was watching. How embarrassing!
