Sylvester Stallone and Bruce Willis reportedly challenged each other to an arm wrestle during a recent night out.
The Hollywood tough guys were enjoying a meal with their respective wives, Jennifer and Emma, at Hollywood's Il Piccolino restaurant, when they started arguing about who was in better shape.
So Sylvester, 65, challenged 56-year-old Bruce to an arm wrestling match which the 'Die Hard' actor quickly accepted and the pair then swept aside glasses, cutlery and plates to lock arms and start their fight.
According to the National Enquirer magazine, diners at nearby tables were initially stunned but as soon as they recognised the wrestlers they started cheering and Bruce and Sylvester grunted, groaned and wheezed for several minutes.
However, the men's wives were not impressed and shouted: ''Break it up!'', which they duly listened to.
Soon after their meal, Sylvester went into hospital to have an operation on his shoulder, although it is not thought to have any link to his night out with Bruce.
