Nate is set up to go on a blind date with Susan, only when he goes to pick her up, he picks up Marni, who was set to go on a different blind date. After talking through dinner, they realize they are perfect for each other, but also realize that they are on the wrong dates.

To make it up to Marni for throwing Todd out on their first date, Nate decides he will spend a day hanging out with Todd. However, Nate doesn't really want to hang out with him. Nate makes up excuses to avoid Todd, but Marni ruins his plans. Todd joins in on a basketball game that Nate and Bowie are playing. Todd continuously harasses Nate, causing Nate to bring out his true feelings about Todd.

On the night before, Marni informs Nate that the next day is her birthday. Nate goes out scrambling for the perfect gift, but is always outdone by Todd. When Nate finally has the perfect gift, he can not give it to Marni because they keep getting interrupted. But when he finally does, it brings the two closer together.

Todd, in an attempt to break up Nate & Marni, sets Nate up by getting him drunk, and placing him in bed with the person he has a lot in common with.

Nate wakes up in Natalie's bed, and quickly gets out of there. He later tells Marni, and about a kiss shared between Nate & Natalie. Marni decides she needs to kiss a guy to be even, which leads to Nate and Marni "breaking up". However, Marni is reluctant to give up, and chases Nate down, who says his speech was only to say he is sick of Marni's behavior, and that they will be together forever.
