Carrot Top is hilarious if you want to see a show.

Last time I was there, we went to an exhibit called "Bodies" at the Luxor. It's very interesting. It's full of preserved bodies, body parts and organs. The coolest thing to me was a model of all the blood vessels in a human arm/hand. They injected a substance into the blood vessels that solidified. Then the flesh and bone was dissolved in an acid leaving only the blood vessels behind.

The Hoover Dam is a must. We also like walking the strip. Next time we are there, I'll have to check out the Atomic Testing Museum. That sounds interesting.
