Jump the shark: The precise moment when you know a program, band, actor, politician, or other public figure has taken a turn for the worse, gone downhill, become irreversibly bad, is unredeemable, etc.; the moment you realize decay has set in.
eg. Tom Cruise jumped the shark the moment he jumped Oprah’s couch.
Enter, Hot Tub Time Machine. Yes, this is really happening. (Feb. 26th 2010)
Pros: Clark Duke (of Sex Drive Fame) + John Cusak (thankyou Serendipity and Runaway Jury), + Craig Robinson (even if you aren’t a fan of The Office, you can’t deny the awesomeness of Zach and Miri Make a Porno)
Cons: the movie is about a hot tub time machine. Thank you, Hollywood.
