Brad Pitt may have put the boom-boom into Jonah Hill's heart.
The 47-year-old actor apparently decided to pimp his young "Moneyball" co-star's on-set ride by turning it into a tribute to the 1980s pop duo Wham!.
"I got my own golf cart just for me and he thought it would be funny, because he knew I was so proud of it, that no one else could drive it, that he would mess with it," Hill, 27, said recently on "The Late Show with David Letterman."
"Earlier in the film, when were shooting, he decided that I love the band Wham!," Hill said. "So I go into my office and there's a framed picture of Wham! and everyone laughs. So now I walk outside after a really dramatic scene with myself and Brad and Philip Seymour Hoffman and my golf cart, my beloved golf cart is shrink-wrapped bright pink. He turned it into a Wham!Mobile."
George Michael and Andrew Ridgeley made up the pop duo Wham!. The two sported big hair and flashy clothes and spurred the 1984 hit "Wake Me Up Before You Go-Go."
Michael went on to become a Grammy-winning solo singer and has made headlines for a slew of drug and alcohol-related arrests in recent years and was charged with "engaging in a lewd act" after being detained outside a public men's restroom in Beverly Hills, California. He poked fun at the incident in an episode of Ricky Gervais' series "Extras."
Hill showed Letterman a picture of the cart, which contains the message "I'm Jonah Hill and I love Wham!" as well as a picture of the actor and Bitt depicted as the members of the pop duo.
"Moneyball" hits theaters on Friday, September 23 and is based on a true story. Pitt plays Billy Beane, general manager of the Oakland Athletics baseball team, who utilizes a new method of scouting players that mostly involves analyzing game statistics. Hill portrays his assistant, Peter Brand, while Hoffman plays the team's manager, Art Howe.
Hill said he and Pitt have a "big brother-little brother" relationship in "Moneyball," which carried over into real life, addng: "We would drive these golf carts all around and smash into each other and it was really fun and stupid."
Pitt, he said, is "the coolest guy."
"Everyone works with some big movie star and they try to kiss their butt or whatever when they're on TV," Hill said. "(Pitt) is genuinely is a wonderful, charismatic, intelligent, talented man. He also is incredibly skilled at pranking people."
Hill worked for his friend's brother, folding boxes, before he caught his big acting break with David O. Russell's 2004 film "I Heart Huckabees," which stars Dustin Hoffman. Hill later starred in Judd Apatow's comedy films "The 40-Year-Old Virigin" and "Knocked Up" and had leading roles in "Superbad" and the 2010 film "Get Him to the Greek," which stars Russell Brand and Diddy.
