When I was about 10, My mom, sister and I were visiting my grandparents. They were all talking when I notice a pink moving thing coming out of the belly of my grandmother's dog. Now, my cat recently had worms, and I was certain my grandmother's dog had a giant worm. Horrified, I asked loudly, "grandma, what is that?!" And pointed to it. To which my grandmother responded, slightly annoyed, "That's his penis."
I was terribly embarrassed.
