I've got a few. I just saw a rerun of one of my favorites.
From Criminal Minds, Prentiss is taking about her cat, Sergio, whom she passed off as her new boyfriend, when talking to her therapist. She says to Hotch, "He is the perfect man. He doesn't hog the covers, and he poops in a box."
There are too many from Firefly for me to just them all.
I'll add a more serious one, from Star Trek TNG: The Wounded:
"When one has been angry for a very long time, one gets used to it. And it becomes comfortable, like... like old leather. And finally... becomes so familiar that one can't ever remember feeling any other way."
Bandit #1: "And I think maybe you're gonna give me a little one-on-one time with the missus."
(Husband) Jayne: "Oh, I think you might wanna reconsider that last part. See, I married me a powerful ugly creature."
(Wife) Mal: "How can you say that? How can you shame me in front of new people?"
(Husband) Jayne: "If I could make you purtier, I would."
(Wife) Mal: "You are not the man I met a year ago." (they suddenly draw their guns on the bandits, Mal slowly pulling his bonnet off)
Mal: "Now think real hard. You been bird-dogging this township a while now. They wouldn't mind a corpse of you. Now you can luxuriate in a nice jail cell, but if your hand touches metal, I swear by my pretty floral bonnet: I will end you."
(Duffy laying flat)
Raylan drops the bullet on Duffy and says, “The next one’s comin’ faster”
I love the end of Raylan Givens' facedown of Wynn Duffy in the episode "Full Commitment" of JUSTIFIED:
The next time we have a conversation, there won't be a conversation.
... which is followed up in a subsequent episode "The Gunfighter," when another Deputy Marshal drags a reluctant Givens to interrogate Duffy. Givens says he doesn't to go because the last time he talked to Duffy, he told him about the no conversation next time. The other Marshal says Duffy won't remember the remark and anyway, if he does, just say it's a different conversation.
So when they find Duffy, the first thing Duffy says to Givens is, "I recall the last time we spoke, you said 'the next time we have a conversation, there won't be a conversation."
Givens looks relatively nonplussed and then says "This is a different conversation."
"I'll carry your books, I'll carry a torch, I'll carry a tune, I'll carry on, carry over, carry forward, Cary Grant, cash and carry, carry me back to Old Virginia, I'll even 'hari-kari' if you show me how, but I will not carry a gun!"
Les: The... the crowd is uh... curious but well behaved. And I think I hear something now. Uh... The crowd is moving out into the parking area. And... oh yes! I can see it now. It's a... it's a... helicopter and it's coming this way! Andy: A helicopter? Les: It's flying something behind it and I can't quite make it out. It's a large banner and it says H A P P Y... T H A N K S... giving... from W... K... R... P! What a sight, ladies and gentlemen. What a sight. The 'copter seems to circling the parking area now. I guess it's looking for a place to land. No! Something just came out of the back of a helicopter. It's a dark object, perhaps a skydiver plummeting to the earth from only two thousand feet in the air... There's a third... No parachutes yet... Those can't be skydivers. I can't tell just yet what they are but... Oh my God! They're turkeys! Oh no! Johnny can you get this? Oh, they're crashing to the earth right in front of our eyes! One just went through the windshield of a parked car! This is terrible! Everyone's running around pushing each other. Oh my goodness! Oh, the humanity! People are running about. The turkeys are hitting the ground like sacks of wet cement! Folks, I don't know how much longer... The crowd is running for their lives. I think I'm going to step inside. I can't stand here and watch this anymore. No, I can't go in there. Children are searching for their mothers and oh, not since the Hindenberg tragedy has there been anything like this. I don't know how much longer I can hold my position here, Johnny. The crowd...
OMG I miss that show. Will they ever get it on Netflix?
