Have you guys seen the latest Sprint / Nextel commercial where the two guys are arguing about a BLT sandwich?  These two guys are in what looks like some kind of factory where sirens are going off and one guy leans to the other and says

Guy 1: If they are going to mayonnaise on a BLT they ought to call it a MBLT. It's only right
Guy 2: In that case they should call it a BBLT because of the bread.
Guy 1: No, in the sandwich world, the bread...

Guy 1 does the walkie talkie thing into his Sprint / Nextel phone saying "Valve 347" and continues

Guy 1: ... the bread is a given.

You then see men in full protective suits rushing to turn off valve 347 and in turn stop the sirens.  It cuts back to the two men arguing and you can hear over the walkie talkie "We did it! Yahoo! ahahah".  The argument continues.

Guy 2: Mayonnaise is a condiment. Condiments don't get initials.
Guy 1 (looking both aggravated and dumbfounded): Well who made up that rule!?

The last two lines just floor me every time...  
You can watch it on Sprint's website.  The commercial is sandwich one and I find it hilarious. What do you think?
