This Twitter bet by Gerard Pique could have cost him a staggering €7m

We've all made daft bets we come to regret - nowadays they all seem to be on Twitter.

Take the West Ham fan who now has the Liverpool scoreline tattooed on his arse as a perfect example. The app should come with a 'do you really want to tweet this' warning at the very least, if not a full scale breathalyser to stop people tweeting silly bets. But it's not just fans that make outlandish wagers on Twitter - footballers are at it too. Gerard Pique put a quite-spectacular effort up the other day after seeing the strange scoreline coincidence in Serie A over the weekend, according to the Mirror. With four games finishing 2-2, the Barcelona star posted that if the day's final two games - Lazio vs Udinese and Inter vs AC Milan - finished with the same score, he would buy everyone who retweeted him a Barca shirt. https://twitter.com/3gerardpique/status/643088925125439488 When 80,000 people retweeted him, he must have been s**ting his pants. Doing some rough maths, a shirt costs €90 - so he was staring down the barrel of a €7.2m bill. Luckily for him, fate wasn't on the side of the fans and Lazio saw off Udinese 2-0 and Inter beat AC Milan 1-0.
