Actually, during the last 2 years of high school my nickname (given to me by others) was Cookie Monster.
Found at The Itinerant Librarian.
You’re sweet (but not too sweet) and you fill other people’s lives with tasty bits of awesomeness. You’re no perfectionist – in fact, you’re a bit disorganized – but your friends find your easygoing personality irresistible. You’re so popular and loveable that even when you’re having a bad day, people still like having you around.
This is kind of funny because it is representative of me in some ways, but also wrong in so many others. Perhaps this misperception is what led to last week’s weirdness. 
And where the heck are the walnuts on top of that cookie?
No kidding! I was called cookie monster for the first several years of my … er, I’m still called cookie monster sometimes
Dare we ask why you were called “Cookie Monster?” And I can do without the walnuts, but I certainly know a good number of people who would like them. Maybe half and half on the batch?
Best, and keep on blogging.
Nice to know, John.
Yes, Angel, you can ask. Seeing as others named me such I assume it was due to my eating more cookies than the average high schooler. And Cookie Monster was a little more in the cultural focus at that point; he may have still been eating only cookies then, too.
I, too, am more than happy to have a good cc cookie without nuts. And some have allergies which I fully understand and am happy to accommodate. So either way is good with me, but I prefer them with nuts. Now. Didn’t used to.
Of course, I bet that was in the days before Sesame Street put Cookie Monster on a diet; one of the saddest moments in children’s TV if you ask me.

Yes, Angel, I believe it was (both of your points). I started to put in a date but then I figured there’s enough (too many??) explicit references out there to my age as I get ready to look for jobs.
