Gambler #2: Three-to-one you do.
Gambler #1: You're on!
Gambler #2: You lose.
Some people will do just about anything for a bet, so wagers are a great excuse to have characters do just about anything. Just have someone bet them they won't. Regardless of how crazy the challenge, and how disproportionate (or nonexistent) the reward, they will go to any lengths to win. Maybe they want to show up their rival or make a point or maybe they just want to win the reward. Either way they're sure to have a whole lot of adventures trying to succeed, especially if their rival is trying to sabotage their efforts. And just maybe they'll end up learning that there are some things that are more important than winning the bet.
Examples only count when the bet is a major part of the story, if not the whole reason for the plot. So if The Hero and The Rival have a bet on who will win the sports tournament they've entered, that doesn't count because winning the tournament is the objective, the wager just adds to the rivalry. It doesn't have to be the main characters who make the bet though, they could equally be the ones being bet on, so long as the bet is the reason for the plot. May be made by the Professional Gambler or The Gambling Addict, or be part of an Absurdly High-Stakes Game. More minor examples may count as a Side Bet.
A common Romance or Romantic Comedy version of The Bet is when a character is bet that they won't/can't win over/date/sex up a certain lady. The guy will almost inevitably end up developing genuine feelings for the girl, and the girl will just as inevitably be pissed off when she finds out about the bet. This may lead to The Grovel when he asks for her forgiveness.
Compare to On One Condition, which is essentially a dead person betting their estate that you won't fulfill the conditions of the will.
- There are a number of stories and films called The Bet which use this trope.

The expression on the brokers' faces was priceless.

- The basis for several Roald Dahl short stories, the most famous of which is probably "Man from the South". In this story, an old man named Carlos offers a boastful American boy his Cadillac if the boy can strike his lighter ten times in a row. The catch is that if the lighter does not light ten times in a row, Carlos will cut off the boy's left little finger. It fails on eight.

Luckily, Lando was trying to impress Mara Jade and gave it back.

- A recurring element of Barney's character on How I Met Your Mother is that he is a gambling addict. This comes in two flavors.

- Drake & Josh:
- One episode titled "The Bet" had Drake and Josh betting they could quit their bad habits longer than the other.

In the end, when neither Monica nor Rachel are able to remember what Chandler's job is, they lose.
- An episode of Barney Miller had a bet between Yemana (to stop gambling) and Harris (to stop smoking) to see who could last the longest. At the end of the episode, when the couple from the main plotline settled their differences, there was this exchange:

Yemana: You're on!
Harris: You lose. (lights up)
- CSI: 'Hitting The Cycle' centered on a betting pool regarding who would investigate the last in a complete set of death circumstances: accident, homicide, suicide, and natural, all in one shift. Superdave, the coroner's assistant, found the long-sought-after natural, though only because another assistant died of a brain aneurysm at the episode's end. Most of the CSIs lost the wager by betting on themselves, and Catherine bet that no one would complete "the cycle" at all, on the grounds that natural deaths are rarely investigated by law enforcement. Doc Robbins, shrewdly, realized that David was the only member of the shift to look at every body that came in, and won the pot.

Tennyson will only be allowed to communicate in writing, and the bet will end if he just makes a sound, but if he manages to stay quiet until 10PM on June 3rd 1962, he'll earn $500,000. By the end, despite being offered $1000 or $5000 to stop early and being told rumors about his wife cheating on him, Tennyson manages to stay quiet for the whole year. Taylor relents that he doesn't have the $500,000 to give him and that Tennyson has proven himself to be the better man...only for Tennyson to reveal that he'd secretly had an operation done to sever the nerves to his vocal cords just before the bet.
- In one episode of I Love Lucy, Lucy makes a bet with Ricky that she can go without buying a new hat for longer than he can go without losing his temper.

Black would win it all back if the Hurricanes won, which gave Garkos, who owns the Opposing Sports Team, another motive to sabotage the Hurricanes.

The game ends up being a limbo competition, and Mandy sics Mr. Snuggles on Grim right as he's about to go under the bar, causing him to bump into it and lose. Amusingly, after the pilot episode, Mr. Snuggles is very rarely mentioned, if at all.

And he did it.

Jeff and Britta get into an argument on whether men or women are better at going without sex, so they make a bet to see which of them can go the longest. Note that they're not dating each other; they're just betting on sex in general.

- Bet Me by Jennifer Crusie (pants version) Subverted, in that Cal didn't actually make that particular bet. As he says repeatedly. Played straight in that he did make multiple other bets (and passed the profits straight on to Min; is that another subversion?).
Min smiled cheerfully at David. "I know Cal won it," she said, "but we have this unwritten rule that I get all the money he wins on me. I'm picking up quite a bit of spare change that way, so this" She looked at the check and almost dropped her comforter. "Oh, my God.""Not ten bucks," Cal said, yanking up the comforter before she lost it.Min looked up at him, appalled. "You bet ten thousand dollars you could get me into bed?""No," Cal said.

- In Guys and Dolls, Nathan bets Sky that he won't be able to get Sarah (a pseudo-Salvation Army lassie) to go to Havana with him. Romance ensues, but Sarah returns to find her mission raided because Nathan has been holding a crap game there.

However, in a subversion, MJ doesn't care in the slightest, even making crack to Flash about the fact that he lost. Of course, it helps that she's probably aware that Peter's Aunt May set up the whole thing, plus MJ knows that she's hot and Peter would have been willing to go out with her, bet or no bet. Flash, not wanting to be the only one dresses as a cheerleader while honoring the bet, forced his teammates into similar outfits.
