iKiss is the tenth episode of the second season of iCarly, the episode originally aired on January 3, 2009. The episode was the first iCarly episode to reach number #1 in the iTunes TV Shows chart.
The kiss between Sam and Freddie in this episode would serve as the setup for the season three episode iThink They Kissed, when Sam, who was getting a broken tooth removed, accidentally tells Carly about the kiss while disoriented by laughing gas. Sam and Freddie kissed again in iOMG, revealing that Sam is in love with him.
When Sam overhears Freddie admit he has never kissed, she decides it would be fun to expose this confession on Carly's web show, until the rampant humiliation he receives at school makes her regret her decision.
