I love pet theories so I hate to disagree. I've personally said the word "Legos" about 1M times in my life and it's mostly because Legos always come in groups, groups with a lot of items. You have to have a plural word to refer to them. Also (child of the 70s) I am certain that I was calling mine Legos before I even knew about Eggo waffles. Third - boy I'm really piling on, sorry - I don't think I've ever referred to multiple Eggo waffles as "Eggos", probably because there's already "waffles" for that.
