The stripes were a dead giveaway, Relative Number One! The local police would have assumed that Heathcliff was the Headless Garbage Man, but you go and give it all away because you forgot to change.
I like how the cop is adjusting his belt. It must be too tight. Clearly he's dissatisfied with his status as one of Gallagher's Weeble people who wiggle and wobble but never fall down. Not all cops are doughnut sucking, coffee swilling authoritarians, Mr. Gallagher.
