So the Colon Cleanse people are onto me

I have eaten too much candy and feel completely sick. 

So, of course, I just got another Colon Cleanse email.  This one has an even better claim than the others.  It says I can loose 20 lbs overnight!  

Seriously? 20 lbs overnight? Are they going to cut off one of my legs?  

Loosing a leg sound slightly more appealing than the way that 20 lbs is really coming off if I use their product.
