Ashton Kutcher

The Show: Punk'd
The 411: Fans will be disappointed, but Hollywood can give a collective sigh of relief – this debut will be Ashton's last after eight seasons of celebrity pranks.
End of an Era? Most likely, yes, but it's not the first time he's called it quits. In 2003, Ashton announced that the series was ending after two seasons, prompting celebrities to let their guard down. For now Jo Jo, Hayden Panetierre, Zac Efron and others will be the last ones to get duped, culminating with the Punk'd Awards.
When to Watch: Tuesdays, at 9 p.m., on MTV
