is this a joke?

Sometimes, I will try a random phrase with .com at the end of it. Tonight, I tried http://www.lol.com/ and saw something amazing.
As many of you know, LOL stands for Laugh out Loud. It is an all purpose expression in the world of instant messenger, used for a variety of things. Sometimes it is used appropriately.
So, LOL.com has a joke at the top of the page (duh), a bar saying “tell me another” and then a box with an ad from amazon.
The book featured in the ad is “The Truth” by Al Franken.
Is this supposed to be funny?
