Deliberate mistake: The episode begins with a football game in pouring rain. After the winning goal is scored, the crowd shots show the cheerleaders' hair wet and their uniforms completely dry. (00:01:50)
Continuity mistake: As Lex is chalking his pool stick while talking to Dominic about cutting 20% of the workforce at the LutherCorp Smallville plant, there is a red snooker ball on the wall rack missing from the second row. When Lex walks over to the other end of the pool table, the camera shot changes back to Dominic, now there is a ball missing from the top row, which was not missing before.
Continuity mistake: While Clark and Jonathan are talking about Clark being on the football team, Jonathan puts his hands on Clark's shoulders. Between shots, the position of Jonathan's hands on Clark's shoulders repeatedly changes.
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.
