I wasn't born yesterday 

Something you say in order to tell someone that you are not stupid and are not easily deceived.

Mom: Timmy, what was that sound?
Timmy: Idk mom, it was probably Johnny masturbating again.
Mom: I wasn't born yesterday. Get your damn girlfriend out of your room.

Dr. Yesterday 

Someone who is hopelessly un-hip & out of date.

Phil: Hey Norm, I'm thinking of getting tickets for the Stevie Ray Vaughn concert for me & my 20 year old g/f.
Norm: Hey Dr. Yesterday, I think she'd rather go to to see Gwen Stefani. Plus, just so you know, Stevie Ray Vaughn's been dead for like 15 years, cockhead.
Phil: Oh...

yesterday 

When someone tries to make their incompetence your problem by demanding the impossible. When asked when they need something done they respond with "yesterday." This response generally baffles the questioner because it is impossible, inconsiderate, annoying, pompous, and lame.

Bill: When do you need this project finished?
Steve: (matter of factly) Yesterday.
Bill: (thinking) What a lazy, pompous, piece of sh*t a-hole.
