8 yr. old: Mom can I have one of those chocolate drinks in the fridge?
Mom: No, those are slim fast drinks your Dad is using to try and take off the few pounds he gained over the holidays.
8 yr old: Oh man! I wanted to do that with my Special K Challenge!
Perhaps this dear son has been watching to much tv over the last few days. The advertisers have managed to convince a child (who does not need to lose weight) that their products are so fantastic even he must try them. A little scary if you really think about it.
