Followed by sneaking into Paul's apartment. Raiding the fridge. Sniffing the clean clothes. Bouncing on the bed. Having an imaginary conversation with a snapshot of Paul. Then having a real conversation with Sarah that includes her baaaaaa-ing like a sheep. Made even funnier when you remember that Dolly, the world's first successfully cloned mammal, was...a sheep.
Alison's sex scene with Aynsley's husband Chad is hilariously awkward. While they're getting it on in the back of his car, a woman and her children walk past, notice what's going on, and scurry away scandalized.
Alison singing Meredith Brooks' "Bitch" at the top of her lungs - really, all of her rebel phase is pretty hilarious.
Alison showing up at Felix's door drunk.
Alison (meekly): Bad things have happened to me...
Sarah comforting Alison after her breakdown and her attack on Aynesley.
Sarah: Did you kick her ass? Alison: ::sniffles:: Yeah, yeah I guess I did.
Sarah prodding Felix with her foot while he's trying to read is hilariously Adorkable.
Alison cleaning Felix's place and his reaction to it.
When confronted with an intervention, Alison goes to swallow some pills. Felix grabs her hand and asks for some too.
Even better is her introducing him to the intervention group.
Alison: This is Felix. Felix: Gay friend. Alison: Acting coach. Pastor: Oh, that's alright here. Felix: Which one?
The expression on Felix's face when Alison says she'll only talk to him when she's holed up in the bathroom is priceless.
From the first season finale: UP YOURS, PROCLONE
Felix's confrontation with Delphine when she first shows up. He gives her an extremely judgmental once-over (blonde, curly-haired, gorgeous French scientist wearing a white tank-top) and sums it all up with a wonderfully catty:
"Well. Now I get it."
He then turns around and shouts at Cosima, on the other side of the apartment:
"IT'S DELPHINE! ...She's got baggage!"
The rehearsal for the musical Alison's in.
Alison sending Felix a gun hidden in a bouquet of flowers.
Felix: Well, those are so Alison.
Sarah sends a body double to fool the Neolutionists, who gives them this message: She says "Up yours".
Sarah dresses as Cosima to bypass the Neolutionists, only to be greeted and kissed by Delphine. Her face is just priceless.
Funny Background Event: When a bleeding Helena staggers into the hospital, she passes a sign pointing the way to "Genetics."
Donnie's hilariously bad spying on Alison; Leekie's visible frustration at his incompetence is hysterical.
Felix accidentally stepping in a cow pie and complaining about wanting to get back to civilization.
Cosima and Delphine sneaking into Leekie's lab like a couple of naughty schoolgirls? Adorable. Cosima imitating Leekie? GOLD.
Although unbeknownst to the others, Delphine and Cosima are holed up in the lab attempting to find a cure for Cosima's illness, Felix attributes Cosima's lack of communication to her and Delphine being caught up in a "transgressive lesbian geek-spiral".
Helena in Fee's loft, snarling at him like a cat.
Fee sending her off to the shower: "Just don't kill my rubber duckie."
When Fee brings Helena to Art's apartment for safekeeping:
Felix: Look, Helena, he wants to help you and Sarah. Helena:He lies down with pigs. [makes oinking sounds] Felix: Aaaaand that's my cue to leave...
Felix drugs Vic's tea, causing him to fall face first into a table covered in glittery arts and crafts supplies. Felix, Sarah, and Alison spend the rest of the episode trying to hide his unconscious body.
Sarah (pretending to be Alison) doing a role playing exercise with Donnie for Family Day at the rehab center. Things get confusing very quickly.
Donnie apologizes to Alison for spying on her, lying to her, and hating her mother. Alison responds by saying that everyone hates her mother, as if it's the most obvious fact in the world.
Extra funny from Alison: Donnie just freaking killed a guy, and Alison's more worried about the mess in the trunk. Sure, it's probably an evidence thing too, but Alison's just so casual and prissy about it.
In the next episode, Donnie confronts Angela and Vic spying on him and Alison. After he threatens them, he takes a picture of the two as proof, and Vic can't help but flash a peace sign as the photo is taken.
Alison and Donnie's domestic bickering while disposing of Leekie's corpse makes for some really great Black Comedy, especially when Donnie complains about how gross it is and comments that Alison is better at handling manslaughter than he is. Then there's Alison wrapping the body in a girly plastic tablecloth and bright pink tape.
The Clone Club Dance Party in the second season finale. Also counts as a sweet moment as well because of the sisters and Felix dancing together.
Art gets Helena back in his apartment, and he and Felix question her about the ranch she burned down in the previous episode. Felix and Helena's exchange comes off like a disappointed parent lecturing their kid.
Felix: Helena. Did you burn down the fish people's ranch?
