Trivia: Two and a Half Men
- Actor Allusion:
- Charlie, every now and then, goes to a psychiatrist played by Jane Lynch. In "My Puppy's Dead", he and Alan go home after one visit and watch Glee, to which he responds "that tall blond in the red track suit is freaking me out".
- In "People who Love Peepholes", Alan says that "when I was was in high school, I was dating a poster of Molly Ringwald". Before Two and a Half Men, Jon Cryer was most famous for Pretty in Pink, where his character, Ducky is hopelessly in love with Ringwald's.
- In the season 12 premiere, Alan dresses as Ducky for Halloween.
- In "A Giant Cat Holding A Churro" Alan confronts his girlfriend Lindsey, played by Courtney Thorne-Smith, with her playing in a softcore porn movie when she was younger. She then tells that the producer had said he could get her on Melrose Place. Courtney Thorne-Smith was a Melrose Place regular for the first five seasons.
- A somewhat atypical example. When Alan starts believing himself to be Charlie out of grief, he ends up institutionalized, and imagines he's calling up hookers like Charlie did. Upon "hanging up", he utters Charlie Sheen's own infamous post-firing catchphrase "Winning!". (This is as much an allusion and a jab at Sheen, of which season 9 has plenty).
- In "You Do Know What the Lollipop Is For", Walden comes down the stairs, and then is taken aback when he can't remember why he came downstairs. Alan suggests "Maybe too much (imitates inhaling a joint) oh hey, dude, where's my car?" Ashton Kutcher starred in the 2000 stoner comedy Dude, Where's My Car?.
- A 2013 episode featuring Emily Osment as Ashley, the promiscuous teenage daughter of a middle-aged woman Jake is dating who Jake cheats on for, has Alan arguing with Walden about the affair in front of her. Walden sarcastically calls her "Hannah Montana". Emily played Miley Stewart's BFF Lilly Truscott in the Disney series. May be even more of an allusion as Jake is moving on from his relationship to Missi at the time.
- In "How to Get Rid of Alan Harper", Walden's girlfriend proposes a game of "bang, marry, kill", with Angelina Jolie, Mila Kunis and herself. Later, when she cancels her date with Walden and leaves, he says: "Better hope I don't run into Mila Kunis!" She responds: "Yeah, like that's gonna happen". Mila Kunis is Ashton Kutcher's girlfriend in real life.
- "Lan Mao Shi Zai Wuding Shang", where Mila Kunis guest stars has as Vivian, has several.
Walden: That's a beautiful name.Vivian: Thank you. My parents got it from that '70s show. What was it called? Maude!
- When she introduces herself:
Vivian: So what's your deal Walden? You're a good looking guy, rich, Malibu beach house... I bet you only date hot actresses.Walden: God no, I'd never date an actress. They're all crazy.Vivian: I'm sure they're not all crazy.Walden: Trust me, they are.Vivian: I don't get this whole fascination with celebrities anyway. I mean who cares who's dating whom or who's engaged to who, or who has a sex tape that no one will ever, ever see?
- When Walden invites her to stay the night because it really started to rain, she says: "It's just a little water. I'm not gonna melt. (spoilers for a then-recent film of hers) It's not like I'm the Wicked Witch of the West."
- When they talk about dating:
- Detective Wagner in "Of Course He's Dead" is played by Arnold Schwarzenegger. Alan ends a conversation with him with "Hasta la vista", and when Christian Slater claims that he's not Charlie Harper, Wagner says "Yeah, and I'm the Governor of California."
- Creator Backlash: Angus Jones (who played Jake) left the show at the end of season 10 after he converted to Seventh-Day Adventism. He now treats it as an Old Shame, claiming that it is immoral and that he had been a "paid hypocrite" by starring on it.
- Creator Breakdown: The circumstances surrounding Charlie Sheen's exit are an explosive example.
- The Danza:
- Charlie Sheen as Charlie Harper.
- Paula Marshall as Paula, Alanís Transsexual girlfriend from ep. 9-10 of season 11.
- Fake American: Rose, played by New Zealander Melanie Lynskey.
- Hey, It's That Gal!: Berta's granddaughter is Mikaela Banes!
- Hey, It's That Guy!: Robin apparently retired from his crime-fighting business in Gotham to go back to LA to give his ex a bit of a shock...
- Hey, It's That Voice!: In the Japanese dub, Charlie Harper is Kakashi Hatake and Rom Stoll.
- Money, Dear Boy: A variation; the main reason why Chuck Lorre pushed the network to commission a pilot was because co-creator Lee Aronsohn would cease to be eligible for WGA health coverage if one of his scripts wasn't put into production very soon. Fortunately for all concerned, it turned out that the network quite liked the pilot...
- Write Who You Know: Charlie Harper's characterization is basically that of his actor, Charlie Sheen. It's even referred to as such by Trifecta.
