The first one is related to the actress with the violet eyes: listo (click to hear the pronunciation) in Spanish means "ready" and also "ok". The cool thing is that sometimes people replace it for LizTaylor :)
A: Hey, when are you finishing using the pc?
B: All right, all right, let me send this e-mail...[sends it]....Liztaylor!
The second one includes a western star: tranquilo (click to hear the pronunciation) means "quiet" and also "relax!", so sometimes people changes its pronunciation and make it rhyme with the actor's name: "tranquilein, John Wayne"
A: Oh my god, oh my god, I accidentally erased my blog...it's all gone!
B: Hey, I know a guy working for Blogger, I'm gonna call him to ask him for a solution...So, tranquilein John Wayne....Do you have something like this in English (or the language you speak)?
