Translation Party is an excellent website if you want some random fun. What happens is you type in a phrase and click the blue button. The site will translate the phrase into Japanese, then back to English, then back to Japanese, as nauseum, until it reaches "equilibrium" - when the English translation stabilizes and stops changing. If it can't find a solution, it will respond with a funny comment and give up.

To give you an example of what happens, I tried this little gem. Insensitive and irreverent? Yes. Funny as hell? Absolutely.
(Yes, I know now that the latter half is incorrect. I haven't been to Church in years, so I hope you'll find it in your hearts to forgive my forgetfulness )

I just typed in a random question and it turned out pretty funny.

The weirder the original phrase, the more insane the translation.
