That's logic for ya.

I took Tarryn to Olive Garden for a special one-on-one date. While we were waiting for the food to be brought out, Tarryn began unrolling her napkin wrapped utensils. Picking up the fork, she pondered aloud, "Hmmm...that's weird, this fork only has three pokey things instead of four."
To which I replied, "Yeah, that's a bit unusual I guess."
"Well, shouldn't it be called a threek instead of a fork then?" remarked my clever 10 year old.

Now why didn't we have logical children make up the vocabulary for the world?!
