After failing to fix Frasier's toilet, he and Niles call some plumbers but soon discover that they are their old childhood bullies, the Kriezel Brothers Danny and Billy.
Tropes:
- Call-Back: Billy was first mentioned in the season 1 episode, I Hate Frasier Crane as a old bully to Frasier. Here, he makes his appearance and shows that he hasn't changed much since then.
- Comically Missing the Point: Danny initially doesn't recognise Niles, and has to be prodded into doing so by Niles reminding him of some of the torments he was subjected to. Upon doing so, Danny chuckles and initially asks Niles if he still keeps in touch with anyone from school as if they were old friends.
- Every Man Has His Price: After he gives Billy Kriezel a swirlile, Frasier saves himself from a beating via a bribe.Frasier: I've never written a check so quickly in my life.
- Friendly Enemy: Played with: Danny Kriezel appears to have viewed his bullying of Niles as just good-natured youthful hijinks, and on being reminded who Niles is greets him warmly as if they were old friends. He does show genuine remorse when he realises how affected Niles was by it, however.
- Hypocrite: Frasier encourages Niles to not seek vengeance on Danny, only to seek vengeance against Billy. In total fairness he does give it a try, but unlike Danny Billy shows no remorse at all about what he did.
- Jerkass: Billy, who shows no remorse for bullying Frasier when he was a kid.
- Jerkass Has a Point: Not for the first or last time, it is pointed out that while Frasier and Niles may not have deserved to be bullied as children, a reasonably fair case can be made that they brought at least part of it on themselves through their unnecessarily pretentious ways:Niles: Look, you're missing the point. I was severely scarred by those experiences.
Danny: Hey, wait a minute. I can't defend everything I did back in junior high, I mean who can? But let's face it; when you show up at school wearing a tweed blazer with elbow patches and carrying a valise, I mean, I think the guilt here is fifty-fifty. - My God, What Have I Done?: Unlike his brother, Danny shows remorse for bullying Niles as a kid.
- Schoolyard Bully All Grown Up: The Kriezel Brothers. Danny has actually matured and is genuinely sorry when Niles explains how being bullied affected him. Billy on the other hand shows no remorse and still laughs about his actions, unaware that Frasier is the victim he's talking about.
- Special Guest: John C. McGinley as Danny Kriezel and Mike Starr as Billy Kriezel.
- Surprisingly Realistic Outcome: Frasier and Niles decide to fix the toilet by themselves, even though they have no experience in home maintenance. When they're done, Frasier tests their handiwork by flushing the toilet - and it overflows.
- Swirlie: Danny Kriezel's method of tormenting Niles when they were at school, which prompts Niles to try and do the same to him as revenge. Later, when Billy unwittingly dredges up memories of bullying Frasier in front of his old victim, Frasier does the same thing, but with more success.
