Yeah, I knew it was a Theif quote, or at least the "Your GP or your HP" part is...although, damn, I just realized that the black in Theif's and RM's is off a bit...
*goes to fix this*
edit: FIXED'D
I also just realized that w/o the response from the vendor, RM's quote isn't really all that funny...But it just fit so well w/the pic I had to use it...btw, here's the vendor's response...
Vendor: Are you on the dope, son? Get out of here before I call the cops on you, punk.
