I would advice you to chage theme of your site and look for better color scheme its looking like a novice user site
Okay not bad but clearly too much space in the sidebar for obvious adverts. People dont like long scrolling pages with adverts
do you really need this adds by google in the middle of the site, and the flash part in the middle, can show the imges without streching them at the background.
I love the TOP Main Menu... LoL... Very nice.. your site is crowded but not make dizzy.. Success for your site.
The flash is not healthy for your site because the Search Engines will have a hard time to crawl it. I've read your jokes, and they are funny. But if it was my site, I would make a summary of each post instead And Make people want to click on them if they want to see more of the jokes. For instance, if your Jokes are from unique contents, you could get higher ranking It also helps for Alexa Pageviews. Just keep posting
