If you watch late night talk shows regularly, you've probably heard about alliâ„¢ by now.

It's a newly approved diet drug that works by blocking fat absorption. If that sounds familiar, it's because the drug is only new in the US. It has been available around here as Xenical® for quite a while now. And, like Xenical and Philos' favorite fish, alli may have certain hilarious unpleasant side effects like gas and oily diarrhea.

That's not news. But what made the late night comics so happy is this little paragraph from alli's website.

You may feel an urgent need to go to the bathroom. Until you have a sense of any treatment effects, it's probably a smart idea to wear dark pants, and bring a change of clothes with you to work

Ahahahaha! That doesn't even need a punchline. They've made a joke out of their own product. And yes, that's really from the official alli website. You can check.

The makers of the herbal diet pill Leptoprin decided to take advantage of the situation by coming up with a nasty attack ad. Enjoy.

Ahahahaha! Poop is funny.
