Reservoir Horses...

Mark felt the expressions on Pitufa, Ruby and Erica in this photo...

Reminded him of something...

To mangle a quote from the movie perhaps the conversation was going like this...

Mrs. Pink (Ruby): Why can't we pick our own colors?

Hector: No way, no way. Tried it once, doesn't work. You got four girls all fighting over who's gonna be Mrs. Black, but they don't know each other, so nobody wants to back down. No way. I pick. You're Mrs. Pink. Be thankful you're not Mrs. Yellow.

Mrs. Brown (Erica): Yeah, but Mrs. Brown is a little too close to Mrs. Shit.

Mrs. Pink (Ruby): Mrs. Pink sounds like Mrs. Pussy. How 'bout if I'm Mrs. Purple? That sounds good to me. I'll be Mrs. Purple.

Hector: You're not Mrs. Purple. Some guy on some other job is Mrs. Purple. You're Mrs. PINK.

Mrs. White (Pitufa): Who cares what your name is?

Mrs. Pink (Ruby): Yeah, that's easy for your to say, you're Mrs. White. You have a cool-sounding name. Alright look, if it's no big deal to be Mrs. Pink, you wanna trade?

Hector: Hey! NOBODY'S trading with ANYBODY. This ain't a goddamn, f***ing city council meeting, you know. Now listen up, Mrs. Pink. There's two ways you can go on this job: my way or the highway. Now what's it gonna be, Mrs. Pink?

Mrs. Pink (Ruby): Jesus Christ, Hector, f***ing forget about it. It's beneath me. I'm Mrs. Pink. Let's move on.

*and the girls wander off to the tune of "little green bag*
