If you're like us and value your sleep, you probably nodded off into your Ambien dreamland before the party started on post-prime time TV. Don't worry; we've got you covered. Here's the best of what happened last night on late night.

Jennifer Lopez was on "The Tonight Show" Monday night, and a couple of interesting things happened. For one, she and Jimmy Fallon played "Catchphrase" opposite actor Anthony Mackie and comedian Steve Higgins. They were all pretty amazing, and ultra competitive, although there were a few uncalled cheating incidents for the winning side. Just saying. (JLo, you were robbed.) That's a key discussion in the comments, if you click on the video - that and the distraction powers of JLo's own bottom line. The fans noticed. But still, it was a great game to watch and it's not like anyone deflated a football or anything. (Too soon?) "That was the best round of the game that I've ever played in my life," Jimmy insisted, once the lightning-fast first round was over. This is a sharp-minded group, controversial non-calls or not.
Also, in her sit-down interview, JLo talked about her live show, and discussed that her mother won a $2.4 million jackpot in the slot machines in Atlantic City. Seriously. Slot machines! This was a while ago, but if anyone didn't need to just win the lottery it's the mother of Jennifer Lopez. Spread the wealth, casino gods! Rob Lowe was on "Conan" and he shared memories from shooting "The Lyon's Den" next to a dildo factory. (True story, Andy Richter was there too.) Rob also shared tips on never aging (he's 50!), and did a live reading of James Franco's poetry, since James did live readings from Rob's first book in front of monuments. Rob still doesn't know why James did it. No one really gets Franco. Jay Baruchel was also on "Conan," insisting he's not always super-high, but he has always had confidence in his looks. His mom raised him to believe he's a catch! Danny DeVito was on "Jimmy Kimmel Live," and he talked about how he got his role in "Taxi" and what's next for him on "It's Always Sunny in Philadelphia." They're in their 10th season of "Sunny" and Danny just loves it. He talks up a Wade Boggs storyline. On a different note, it turns out both Danny and Jimmy were altar boys and they shared stories. Abbi Jacobson and Ilana Glazer of "Broad City" dressed up for "Jimmy Kimmel Live," looking very "Dumb & Dumber" in their colorful tuxes. They discussed details from their Comedy Central show. Jimmy guest hosted "The Bachelor" this week, and he shared a "deleted scene" from when Chris Harrison trained him on how to announce the final rose.
Jimmy Kimmel thinks Benedict Cumberbatch has the best name in the world, but Jimmy was curious to see if he'd be as amazing with a different name. Cue this video with Benedict trying new names. "George Costanza" just doesn't work for him, for some reason. But seriously, this is amazing.
Don Cheadle was on "Late Night with Seth Meyers" and he talked about hanging out with "The Avengers" cast. They also shared an early clip from his career. Ruth Wilson, who just won a Golden Globe for "The Affair," was also on "Late Night," discussing her theater school horror stories, including clown training.
