My friend John suggested a few more HTTP responses that deserve to become panty status:
> 405 Method Not Allowed
> 412 Precondition Failed
> 417 Expectation Failed
Once your mind goes in that direction, every HTTP response code sounds dirty.
> 100 Continue
> 300 Multiple Choices
> 307 Temporary Redirect
By the time you're through with those, even "504 Gateway Time-out" sounds kinky.
Think about THAT next time you're debugging HTTP codes.
