Firefox, Netscape, and Opera: Z! Ma'am yes ma'am! Hup hup hup!
IE: ...wait, what?
Me: *sigh* Z. See here? Z. No, don't look at my finger, look where I'm pointing!
IE: I don't get it. C?
IE: There is no V, dude!
Me: *dropkicks things*
Me: Dear Forums, why the hell isn't this working?
Forums: You need to assign specificity Z, duh.
Me: I. DID. THAT.
Forums: Didn't that work?
Me: No! I've been fighting with it for a day now! For some reason, doing workaround A works, but assigning Z makes IE have brain damage.
Forums: So why not just do workaround A?
Me: Because that breaks the entire rest of the site.
Forums: So why not just assign specificity Z? Duh.
Me: ...I kill you with fire.
Me: Look, I'm writing out detailed references to Z in every function even remotely related to the one you need. You can find Z from 25 different directions now! Sooooo easy!
IE: Dude, what's this 'Z' you keep babbling about? There is no such thing.
Me: IT IS RIGHT THERE.
IE: No it isn't!
Me: This is NOT a fucking Monty Python sketch!
IE: La la la la...
Me: LOOK! Z's! Z's ABSO-FUCKING-LUTELY EVERYWHERE! YOU ARE MORE PACKED WITH Z THAN A NYTOL PIÑATA!
IE: ...I'm sorry, were you saying something?
Me: All right, fine, you win. I give up. *tosses last random Z into totally unrelated corner**
IE: Oh hey, Z! I think you wanted this? *works*
Me: ...I hate you SO much.
Me: Well, at least it's working now and it's over with.
IE: O hey! Did I mention I've got this random one-pixel gap for no discernable reason whatsoever?
* No, seriously, this is like the code equivalent of fixing your engine by pouring a cup of gasoline on the ground next to your right front tire.
