Thomas was trying to convince Nicholas that it is SO FUN to go under the water. Nicholas replied by saying he didn't want the water to get in his nose. Thomas told him to just not breathe through his nose and kind of plug it up inside. Nicholas thought for a minute before excitedly replying, "Oh, yeah...like this!"
I didn't know it was physically possible for someone to plug their nose with their upper lip! I sure can't. I thought I had birthed a unique wonder and excitedly showed Jackson as soon as he walked in the door from work. He shattered my excitement by saying, "You can't do that?" and he proceeded to plug his nose with his upper lip with minimal effort. Crazy.
