A dwarf visits his doctor because of a painful rash on his privates.

He tells that doctor that it only comes when it has been raining.

The doctor tells him to come back on a rainy day.

A few days later, it is raining, so the dwarf goes to see his doctor.

When he enters the surgery, the doctor tells him to take off his footwear and jump onto the couch.

The doctor takes his footwear and goes into another room.

A minute later the doctor returns to the patient and tells him, "I've found the problem and I have cured you."

The dwarf says, "How have you cured me?"

The doctor says, "I've cut 2 inches off the top of your water boots"

It took a while but I got it in the end

Poor dwarf 🤣
