"Cranks a Lot" is the thirteenth short of Foster's Home for Imaginary Friends.
Plot[]
When Mac and Bloo get bored from watching TV, Bloo suggests that they do crank calls, an activity they've done before. At first Mac is against the idea since he was the one that would often get in trouble but is ultimately forced in when Bloo makes him dial the number. Mac quickly comes around and joins in on the fun when he and Bloo prank call Mr. Herriman continuously by imitating farting noises. Mac and Bloo are greatly amused by their joke and Herriman continues falling for their prank each time since Frankie calls him as well in between their pranks. Finally, when an unknown caller makes a fart sound, Herriman tells off the caller and warns the person to not to call again. The caller however is revealed to be a confused (and gassy) Madame Foster.
