Since he doesn't do just strictly Disney voices, I commented and suggested he try Ed, Edd n Eddy . . . now that would be hilarious to hear on the other end of a drive-thru speaker:
ED: I'll have the buttered toast, with extra gravy!
EDDY: Shut up Ed! Can't you see they don't have buttered toast and gravy at this joint?
ED: Drive-thrus can be so cruel! (Sobs)
DOUBLE D: Eddy, please, you're holding up the customers in line behind us!
EDDY: Alright already, sheesh!
