Is that bullshit I smell?

Next time you catch one your friends telling a whopper, call them on it with the new Universal Bullshit Detector watch. While it doesn't really sound off when someone lies, it does simultaneously moo and poop at the same time when you press a discreet little button on the watch. Imagine the quizical looks on their faces when your watch goes off. When they ask what the sound is, you can proudly tell them that it's your bullshit detector watch hard at work! For just $39.95 this watch can be yours.
