One of the funny website that I visit daily to get some laugh.

I went to see this guy for the first time with my wife a few weeks ago. We cried with laughter for 70 minutes. I am still recovering from cheek bone discomfort.

This site has all of Jim's latest news but the video section has PRICELESS material.

Make sure to check the ridiculous section. The russian woman golf cart incident is priceless.

This is one of the most cleverly done cartoon site. Always good for a laugh.

This is one of my original websites from 5-8 years ago. It hasnt changed much since then but it is always really funny if you read through the content :) Maybe one day Bill and I will fix it up quality wise, but it kinda adds to the nostalgia and nonsense to keep it ridiculous.

This is another old site but a classic filled with nonsense, but funny nonsense.
