At 7:36, Dean from Jewelry Bonanza says that 5,000 seconds equals 9 hours, but that is incorrect. 5,000 seconds is actually equivalent to 1.39 hours. To be 9 hours, it would have to be 32,400 seconds.
The word jewelry on Cartman's "Cash 4 Gold" sign is misspelled as "jewerly."
Dean, the Jewelry Bonanza salesman, saying that 5,000 seconds equals 9 hours is an intentional mistake. He is "overvaluing" the 5,000 seconds just like they overvalue the price of the products they are selling.
