Seth Rogen has revealed that Paul Rudd once tried to prank him - but it didn't go well.
Rogen was getting a massage in a Las Vegas hotel when Rudd, thinking it would be funny, took over massage duties.
"He saw me go in and convinced the masseuse to let him take over, thinking I'd notice immediately," the 39-year-old comedian tweeted.
The plan backfired however as Rogen remained blissfully unaware, forcing Rudd, 52, to finish the massage.
