Love me some philosophical gangsters. Very curious what it must've been like growing up in the McDonagh household.

"He was a—what, uh, what d'you call it?"
"Uh, paraplegic?"
"Spastic, yeah."

"Maybe this is the killers five and a halfth victim."
"Go on."
"Maybe he's killed four people before now, and he's maimed another lad. Cut off his legs, maybe. Which would be the half. So this would be victim number five and a half."

"Ah, man, that was fuckin' years ago. I mean, I thought that had all been forgotten about. Same thing happened to Polanski."
"What was it, a sheep or something?"
"It was a llama. You know, I didn't even know it was illegal to interfere with a llama, did you?"
"I would have assumed so, Billy. I mean, what would its parents think?"

Some other great lines:
"I'm Irish, sir! Racism is part of my culture."
"I like sharks. They're soothing."
"I've always wanted a giraffe."
"I'm on tablets, like, for distress. Lithium."
"They're always fuckin' overestimating!"
