My Favorite Joke of All Time

I've heard thousands of jokes in my day. This one is my all-time favorite... at least that I can post about. There are some extremely graphic and disgusting ones I've heard that were really funny but highly inappropriate. This one is borderline, but still makes me laugh when I tell it or hear it. Here it is:

Ava and Ethel were picking potatoes out in a field one day. Ava was really struggling with one of the potatoes and asked Ethel to help her. After a lot of pulling and digging, they finally got a huge 10-pound potato out of the ground.

Ava says, "This potato reminds me of my husband's scrotum."  Ethel replies, "Wow! Your husband's scrotum is that big?"

Ava answers, "No, it's that DIRTY!"

BOOM! Still hilarious!
