I have been eating a lot of sugar free candy recently and it made my bowels loose if you know what I mean. 
Haha I know exactly what you mean! My uncle pranked his coworker once with a bag of sugar free candy. I feel for you, seriously.
It all hit me while I was walking out of an Eddie Bauer store at the mall.  I had to waddle to the bathroom and throw away my underwear.
Oh man that is really bad. I feel sorry for laughing. 
Don't, it was several years ago now and I use it as great story at parties.  People love it.
