Rainbow = Jimmies
Chocolate = Chocolate Jimmies..
Last time we went into Cold Stone, DH ordered Jimmies on his icecream, the lady looked at him like he was from the moon...the other guy asked if we were from the North..we

and tell him NJ originally, and he said that explained it...then told the girl we meant rainbow sprinkles..LOL
DH claimes
there are either "good Jimmies" or "bad Jimmies"..something about them being cheap..LOL
