Continuity mistake: Just before the final play of the game starts there is a shot of the scoreboard. The scoreboard reads 4th and 10 (yards) with 10 seconds to go. The announcer then says it is 4th and 1 with 10 seconds to go.
Continuity mistake: When the offensive line is first shown, as they sit on the bench, the shot is of them from behind. In that shot the team jersey numbers are in this order 89, 46, 8, 66, 1. Then the camera view changes to be in front of the players only now going from the players left to their right is 99, 46, 8, 66, 89.
Audio problem: At the hospital Clark and Jason talk about Clark possibly being on steroids. Watching Jason's mouth reveals he actually says "and a college career." before he says it out loud a few seconds later.
Continuity mistake: Chloe makes an $80 bet with Mxyzptlk at the beginning of the episode. When he pays her in the Torch office, he peels off seven 20-dollar bills for a total of $140 instead of the $160 it should be. (00:09:00)
Continuity mistake: When Clark is in the barn throwing footballs through the tire. He starts out with four footballs on the rack, but after he throws two, there's only one ball left.
Answer: In the comics, Krypto is a dog from Krypton who was used as the passenger in a test launch by Jor-El, Superman's father, before he launched the actual rocket taking his infant son to Earth. Krypto's capsule was involved in a mishap, sending it out of Kryptonian orbit and eventually found its way to Earth where he linked up with the young Clark Kent. Like any native of Krypton, Krypto has superpowers on Earth. In Smallville, the dog is a standard Earth dog who has been experimentally injected with kryptonite, giving him super-strength for a limited period of time, who escapes and links up with Clark (who suggests the name Krypto, ostensibly because of the dog's cryptic origins). It doesn't take too long for the dog's strength to fade, and the Kents decide to keep him, although they ultimately name him Shelby, after a dog that Martha Kent had in childhood.
