WANNA KNOW HOW I GOT THIS SCAR?

Dude! Sharks! I was playing chess with sharks and so had the bastard in check mate. Next thing you know, the thing wanted to get into an arm wrestling match. Best 2 of three. Oh, it was a viscous contender, that shark. Having lost, I was chucked through a plate glass window into the streets, where I was then accosted by a mug of beer and six beautiful women.

What? The scar? Oh... Goose did it. Yeah, don't ask.

A flawless story EXCEPT!!!! Sharks don't have thumbs, and CAN'T arm wrestle. YOU'RE THE KILLER!

I applaud you on a good conclusion.. HOWEVER! You failed to deduce the possibility that these may be evolved sharks with robot arms! Part of a gang of cyborg evolvosharks that eat eggs and peanutbutter for breakfast and THUS work out! Take THAT, prosecutor! I'll see you in the courtroom. Muaha.. MUahaha.. MAUHAAAHHA!!!!!!!!!

I'll get you gadget!!!
