Is this your big thumb?

The other day while Mike and I were driving home, I was looking at my hands and then turned to mike and asked, "Do you call this a big thumb?" He just looked at me like I was an idiot and said, "Um... I call it a thumb?" For some reason I thought all of my fingers were called thumbs so my actual thumb had to be my big thumb. We both laughed our heads off. You might(?) have needed to be there to appreciate it, but I thought it was hilarious.
