Who's that a hiding in the tree trunks? Who's that a standing there afar? Who's that a hiding 'neath the back porch? Who's that underneath the car? Who's that a creeping by the window? Who's that a walking on the roof? Who's that a pecking on the bedroom wall? I don't know, do you? Who's that running by the mailbox? Who's that a letting out that groan? Who's that a sliding down the drain pipe? Who's that a talking on the phone? Who's that a leaving them bathtub rings? Who drank my Mountain Dew? Who's that a talking on the radio? I don't know, do you? Who's that a stinking up the school house? Who's that a getting all the play? Who's that stole my fountain pen? Who ate my mayonnaise? Who's that a hanging around the drug store? Who's that who used my spoon? Who's that a making all the money? I don't know, do you?
