Lump

[Seafood]

I went to see my doctor this morning.
"How can I help you?" she asked.
"I found a lump while I was in the bath," I replied, pointing downwards.
"Oh right," she said, "Take your trousers down for me."
After having a good old feel of my balls for a few minutes, she said, "I can't feel a lump."
I said, "It's on my toe."
