Actor Bruce Willis is said to have hawked a pair of “exploding underpants” on the Late Show with David Letterman, which left his own jeans full of holes.

Willis, 54, who showcased his invention on February 1, had to fight the urge to laugh after the bizarre underpants ‘exploded’ and left two holes below the front pockets of his trousers during the demonstration.

“It’ll liven up any party or any business meeting. Available in briefs, boxers or boxer-briefs for 19.95 dollars… Stand back and learn. When we’re at the lab we like to say, ‘3, 2, 1!’,” the Daily Express quoted him as saying.

The actor then coolly sat back down and drenched his crotch with water.

“I’m like the circus. No elephants, no nothing, just the tent,” he added.
