M&M's have gotten out of control here when I was a kid (1970's), we had plain and peanut. That was it. That was all we needed.
Now, it's plain, peanut, peanut butter (ok, those can stay), caramel, pretzel, almond, Nutella, white chocolate, dark chocolate, toffee, crispy, coffee, mint, mini-sized, birthday cake, coconut, coffee nut, red velvet, mega-sized, cookies & cream, fudge brownie, orange chocolate, chocolate cherry, candy corn, marshmallow, hot chocolate, gingerbread, carrot cake, candy apple, cheesecake, butterscotch, pecan pie, strawberry, pumpkin spice, and about two dozen more I missed!
