To me, a tortellini is highly suggestive of that most ubiquitous of human anatomical accoutrement, the anus. That's not to say that I don't like it very much - tortellini, that is. But, here, look:

Surely you can see the resemblance? Or is it just me?
Now, I'm not sure that I would indulge in a big bowl of Torino-style human anuses (or is it anusi?) unless I didn't in fact know that they were anu - okay - buttholes. It could happen. Here's a story.
I was working late one night trying to get some audio editing done and some artwork finished in my studio space in the City (that's Manhattan for you foreigners.) I was starving, having gotten there at seven in the A of M and worked without breakfast or lunch for nearly twelve hours. I went down to the local deli and rather than get a cold sandwich, I decided it would be best to stoke up on some tasty pasta. I pointed to the penne in the showcase, and the non-English-speaking food worker behind the counter said, "Yes?" I said, "Is that Penne Parmigiana?" He said, "Yes?" I said, "Could I get some?" He said, "Yes?" I waited for him to start a-scoopin', but nothing happened. I figured he needed an amount to scoop. I said "A plate full?" He said, "Yes?" I motioned, he pointed and finally he started to scoop with what, I swear, looked like a cat-box scooper into a Styrofoam container. He weighed it, wrote some numbers on the top of the closed box with a Sharpie and handed it to me. I said, "Thanks! Fork?" He said, "Yes?" and pointed to the register.
There I met a blond, obviously Latino girl, dressed for clubbing, on her cell phone, apparently afraid of breaking a nail. She didn't actually look at me. In fact, she seemed perturbed that I wanted to pay for the food. She was speaking what I thought might have been Spanish or Portuguese at a rapid clip, must have said "Hold on" or something similar, put the phone on her shoulder and shouted to the hapless food worker something like, "What the hell is in this goddamn box, you moron?" At least, that was the tone she exuded. My testes retracted instinctively. He replied in a mumble, so I guess she made an executive decision and punched in $7.99 in her oriental plastic register and said, "$8.80." I said, "It says $7.79." She said one word only and held out her hand, hinging her elbow on her minuscule hip, "Tax." I gave her nine bucks and beat it the hell out of there.
Butt wait: there's more!
I soloed my way back to the fourth floor and into the reception area. I whipped out a six-month old copy of Pro Sound News, popped the top of the Styrofoam container and settled into what I expected would be a worthy reward for a long day's work. I never did get the required and should-have-been-included plastic fork, so I took a plastic knife from the kitchen area as this was the only extant utensil and went back to my comfy seat. I'm looking at a Mackie ad (not Bob Mackie!) and I'm finding the penne a bit on the al dente side every so often. I look down and something catches my eye. Penne shouldn't have suction cups, should they? Here is roughly what I saw:
By the way, here's a Wikipedia entry on Octopuses or octopi - whatever, you get the idea.
And if you want to make your own tortellini in mass quantites, here's an English-language explanation of the factory-model pasta machines from Dominioni. Cool!
