|What's missing, Scoobypedia?|
The clock shop owner worked next door to a jewelry store.
Scooby-Doo! (DC Comics)
He decided to rob the other store, so he dressed up in a ghoul costume. He ducked back into his store, ditched the costume and loot in a grandfather clock, and denied seeing anything. The gang was able to find the hiding place because it was the only clock a little slower than the others.
