|Season 6, Episode 23|
Les buys an Audemars Piguet Royal Oak Offshore watch from a collector for $5000, after carefully examining the watch. However, Seth told Les that he should have done some research on the watch's serial number before he bought it, on the off-chance that it may be counterfeit. Seth's suggestion had fallen on deaf ears for Les, until he showed him the outcome on a verification website, which caused Les to turn livid. After calling the seller back in to confront him (on word that Les was interested in another watch), the seller returned the money, but told Les that he was taken too, by a seller that sold the fake watches to him, before selling them to Les.
