So I've been contemplating, about that nub between your lets. And I though it would be fun to find all the things that I could compare it to. I found a few thing that were about the right size for thickness. But they were too long. And I did find something that accurately portrayed your thickness and length. Haha and it was the tiniest thing I could find in My entire house! Mr. Nubby is what I shall call you from now on!
