SMILING STAN

The bathroom features a wealth of danger. I think it was on an episode of the A Team that I first learned that mixing different household detergents could create an explosion. Bleach and bath cleaner? BOOM! So long, Colonel Decker's pursuit team!

Just now I am coming to the end of a tube of toothpaste, and I started wondering whether mixing toothpastes could have the same effect. Mixing two innocuous cleaning products can blow up security doors for the A Team - why not toothpastes?

One day you're cleaning your teeth and... BOOM!

"Hey, have you seen Stan in accounts lately? Man, what happened to his face?"

"I hear he mixed Maclean's and Colgate."
