Ashton Kutcher's Punk'd Prank Leaves Vartan Unimpressed  4/1/05

Ashton Kutcher has reportedly been forced to ditch one of his pranks on hit show Punk'd, after victim Michael Vartan failed to see the funny side of it.

Most stars - including Justin Timberlake, Halle Berry and Salma Hayek - have laughed when they've discovered their mini crises were fictional situations dreamed up by Kutcher.

But, according US Weekly, Jennifer Garner's ex-boyfriend Vartan was far from amused with the prank chosen for him.

A source says, "They get Michael on a jet, and he finds out the plane is in really bad shape. He wants off, but the pilot and flight attendants won't let him.

"Things are falling off the plane - it's really coming apart and they're telling him, 'No, it's fine, stay.'"

After the prank was revealed, the crew laughed, but a furious Vartan reportedly refused to sign a release for the segment to be broadcast.
