Of Dislocated Jaws and Elongated Necks

We’ve all seen them-a towering, multilayered sandwich made of lots of cold cuts, cheeses and vegetables (and an olive on a toothpick somehow holding the ludicrous thing together)- and drooled over them. Its very hard not to.
Everyone from Garfield to Shaggy and Scooby have been seen making and devouring them in one gulp. But they are named after another fictional character-the husband of the protagonist(?) of the eponymous newspaper strip from the 30’s.
What are they called?

Chain Reaction

Frisky Dingo was laden with references from everywhere. An example:
X-tacle #1: So…who’s read Flowers for A?

X-tacle #2: Oooh, about the kid with all the chains, and the
goggles, and at the end he gets killed with a shotgun?
X-tacles #2, #3, #4: Boosh
X-tacle #1: That’s “B”.
Xtacles #2, #3, #4: Hollywood
Squares!
X-tacle #1: That’s C.
X-tacle #2: Brother of Menelaus!
X-tacle #1: Damn it, that’s D!

Supply A,B,C,D.

Chemical X

XY got the nickname “X” (real name: Eric) when his high school soccer teammates suggested his spiky haircut looked like AstroTurf. Now 42, he has a shoulder-length ponytail, a salt-and-pepper goatee, and a remarkable, intellectual pedigree. Both of his grandfathers won Nobel prizes. His maternal grandfather, Gerard Debreu, was an economist; his paternal grandfather, the famed and controversial physicist Edward Y, worked on the Manhattan Project and is considered the father of the atomic bomb (as well as a model for Dr. Strangelove).

XY was proposing that Z buy Makani Power, a startup that develops wind turbines mounted on unmanned, fixed-wing aircraft tethered to the ground like a kite.

Z has also bought out – reCAPTCHA, BumpTop, Zagat, amongs at least 100 more companies.

What is XY the head of at Z?

With this stud-like family, and amazing qualifications of his own – who is XY?

Hot Brakes?

Junior Johnson was a pioneer in his own right during his run in NASCAR. He discovered drafting as a strategy to reduce drag drastically, for one.
Another innovation was brought on by his friend in the aerospace industry, who wanted him to try out a new material. Amazed by its light weight and strength and because of the rules of NASCAR, he was using it in the late 60’s before anyone else.However NASCAR banned its use when they saw his brake discs glowing red from use, thinking it would cause a tire fire.
What material?

For such a colloquial word, X actually has a very learned past. Samuel Johnson, the compiler of England’s first proper dictionary, claims the word comes from the Latin phrase non compos mentis (“not of right mind”), and was originally a legal term.

The origin of which known insult, not popularly used today.
