Indeed; the spandex uniforms that they used in the first two seasons of TNG were well-known for causing back issues for the actors, because they were so tight. It’s part of the reason why they switched to the two-piece uniform design, with the less skintight top.
Better question: How many people on that ship have multiple butts? 
^ And this is where I came in. 
Or, is it where you butted in? 
Whereas most people have two…
Sounds like the punch line to a Michael Jackson joke. 
I don’t get this. If two plates are placed in front of someone, one with an omelet, and one with scrambled eggs, who couldn’t tell the difference?
To illustrate this, Captain Benjamin Sisko’s father ran a restaurant in New Orleans where they actually cooked fresh food and Sisko himself preferred to cook on Deep Space Nine over synthesizing food from the replicators.
They also stank after a day on the set, and no amount of dry cleaning could get rid of the odor. Yeccch! 
You might as well ask them to distinguish a Spanish omelet from a French omelet (or a Denver omelet, for that matter).
Not much sadder than being the butt of a Star Trek joke.
Have they?
If I saw eggs that had been scrambled and then re-assembled into a solid mass with an apparent outside I would still call it an omelet, perhaps incorrectly. Every time I’ve seen something called “scrambled eggs” it was scattered rather than solid. Then again, I never have scrambled eggs and only rarely have omelets so it’s an academic distinction for me.
There was a brief scene in Star Trek VI: The Undiscovered Country that showed a very conventional-looking professional kitchen on the Enterprise. They were searching the ship for the weapons used by assassins and found two phasers. Someone said, but phasers cannot be used onboard a Star Fleet ship, so someone else proved that these could, by suddenly pointing one at a large kettle and firing it. As I remember, the kettle was vaporized but the food in it was left intact. (I tried to find a YouTube clip of the scene but could not.)
More inconsistencies. 
Phasers have been used on board the ship many times, usually by Redshirts. In “The Corbomite Maneuver,” Janice Rand even heats up coffee using a hand phaser.
Yeesh, don’t those scriptwriters even do their homework? 
So Riker is The Assman?!? 
The impression I’ve had is that replicator food is perfectly fine, even day after day, but prepared food has that something extra. Compare today’s high-end frozen food with something prepared by a chef who knows what s/he’s doing.
There was a restaurant chain called The Velvet Turtle that was a big favorite for some of my co-workers to eat at, especially the women. The menu had over two-dozen lunch entrees – besides their burgers and sandwiches – and I wondered how they could do it. Then after studying the menu, it became apparent every single entree would freeze well and could be finished off in a convection oven.
It’s also sort of swaggery/cowboy-ish, which fits with Riker’s general character.
Even today, people call scrambled eggs with mix-ins “omelets.” Hotels often set up omelet bars where they were just mixing things into scrambled eggs. So it’s likely the term changed to that over the centuries.
Yes, I have observed that, too, that as long as it has veggies in it, and is more or less one cohesive mass, they call it omelet. So Riker’s “omelet” would be consistent with the drift in usage at least in English.
