During the scene where the T.R. kids are driving to the house to steal sod, Jack says "Where' the house Flea?", to which Razzle (played by Red Hot Chili Pepper's bass player Flea), replies "Hey my name's Razzle, man".
When Razzle dumps the slushie into the pickled egg jar, blue syrup goes all down the outside of the jar and puddles onto the counter. In the next shot, the slushie is neatly contained (and well mixed) inside the jar with no mess.
