Ol' JT's crazier than a shithouse rat,I'll give him that much.The main difference seems to be that when the lights hit the rat,he tries to scurry off.
-When they hit JT,he dons a straw boater,grabs a cane and starts doing the "Michigan Rag."
Remember in GTAIII how they poked fun at the game "Driver" by having a cop named "Tanner" who couldn't get out of his car?*
Was JT the inspiration for Ken Rosenberg?I doubt it.
But remember that creative types can hold grudges too,and when they start making fun of you it can last a while.---I'm thinking of when Marge Simpson tried demonstrating against Itchy and Scratchy.That cartoonist looking out the window sure took care of her,heh heh.
*Does the mere mention of this character constitute a spoiler?I'm gray on this.
