Steve: Hey Sumon, I just posted a completely false statement about you on the internet. Check this out! HAHAHAHAHAAHAHA!!!! I'm a crazy megalomaniac!!!!

Sumon: Wow Steve, that's completely untrue and false. That's actually defamation and allows me to sue you for your entire fortune. Not only that, but you're the only luzer around here Steve.
