Goofy can be used in so many ways... and many folks have done a fine job offering examples. I was thinking of that COP pistol but I see Skans beat me to it. (that's what it is, yes?) I think those things are sought after and folks pay good money for them, don't they?
Anyway, I have nothing great add really... but my buddy picked up a Tec-9 in some kind of a horse trade. What a worthless item this thing is. Outside of being a fantastic movie star/ movie prop and being one of the most popular gangland accessories of all time, what jumps out at me like the **** in a punchbowl is how overly large it is -- yet it has a dinky, tiny, worthless little barrel. That stupid little cocktail weenie of a barrel is going to rob every last bit of juice from the already wimpy 9mm's that get sprayed out of it.
All in all, I think it's a completely worthless firearm and outside of a movie set, I can't understand why anyone would want one for any real use. (sure, if you just wanted it 'cause you wanted it, I understand that... but outside of horsing around, what's the actual value in it?)
To me, that's pretty goofy.
