That's why it's called a Big Mac mom......

I remember the first time I went to McDonald's with my parents. I must have been about 14 or so. I was told I could have whatever I wanted, so I ordered a Big Mac. My mom said "Isn't that a bit big for you?" What I wanted to say was, "Ergo, why it's called a BIG Mac, mom...." Of course I just smiled and kept eating.

In the end, I don't think it's the fact that I ordered a Big Mac that surprised her the most, it was how fast I demolished it.
