I should eat fewer M&M’s
A search for “less boobies vs fewer boobies” took me to Grammar Girl’s Quick and Dirty Tips, which said the following:
The basic rule is that you use less with mass nouns and fewer with count nouns.
A count noun is just something you can count. I’m looking at my desk and I see books, pens, and M&M’s. I can count all those things, so they are count nouns and the right word to use is fewer. I should eat fewer M&M’s.
Mass nouns are just things that you can’t count individually. Again, on my desk I see tape and clutter. These things can’t be counted individually, so the right word to use is less. If I had less clutter, my desk would be cleaner. Another clue is that you don’t make mass nouns plural: I would never say I have clutters on my desk or that I need more tapes to hold my book covers together.
Basically. You can go read the whole article if you want. So since I was talking about boobs at a Bette Midler concert, which I could have, theoretically, counted, “fewer” would be the correct usage when comparing it to a Steve Martin and the Steep Canyon Rangers concert. I’m glad we got that cleared up.
