Season 3: Episode 8 - Spoiler Alert

Spoiler Alert: Ted thinks he has found a great girl until the gang meets her and shatters his illusion of how wonderful she is by pointing out that she never stops talking. Once her flaw is revealed, that becomes all Ted can see in glaring clarity, which forces him to break up with her. Angered that Lily has shattered his illusion, Ted points out Lily's annoying flaw to Marshall, and in turn this leads to the rest of gang pointing out each other's flaws. Also, when Marshall loses his password to retrieve his bar exam results, Barney orchestrates an elaborate plan to "help" him recover it.
