Nice Sri Lankan joke site

I came across a nice joke site today url is http://www.udurawana.com . This is from that site

At a party a Mervin S sees a beautiful girl and invitesher to dancewith him...
Mervin S : Can I dance with you?
The Girl : I'm sorry I'm a lesbian..
Mervin S : It's ok. It's ok.. I'm a THOMIAN

There are lots of cool jokes like this in the site. Enjoy ..
