Some people just know how to party, as seen in this crazy bar tab (reportedly belonging to LeBron James) from Vegas a few weeks ago, but Dallas Mavericks owner Mark Cuban isn’t gonna get showed up by LeBron on the court or at the bar. To celebrate his team winning the NBA Finals, Cuban spent $90,000 on a very large bottle of Ace of Spades Champagne. How big is it? It’s 30 liters big and known as a Melchizedek, which is the equivelent to 40 normal sized bottles of Champagne. On top of the huge price tag, he left a $20,000 tip. No big deal, right? Probably not when you’re ranked 459th on the “World’s Richest People” list, according to Forbes.
