K-O Dog: $80 ($6.66 / inch)

To celebrate last year’s National Hot Dog Day (yes, this is a thing) on July 23rd, 2011, the minor league Brockton Rox temporarily claimed the Guinness-officiated most expensive hot dog prize with their $80 “K-O Dog” (or alternatively the “McMullen Dog,” named for the team’s mascot). The tube of meat is deep fried and rolled in truffle oil, coated with a dusting of dried porcini mushrooms, sprinkled with white truffle shavings, and topped with dollops of crème fraiche, caviar, and fresh roe.

At a foot long, the K-O Dog averages out to $6.66 per inch. The team claims to have sold two K-O Dogs. Which is surprising, considering that a ticket to see a Rox game in a premium “super box” sells for $12 on their website -- a little more than one-seventh of a K-O Dog.
