"The Magic Kiss" joke

In a train compartment a young couple and an elderly, somewhat ragged old man were sitting.

The girl looks like she's having some discomfort so her boyfriend asks her, "What's wrong honey?"

She replies. "My head hurts."

Her boyfriend kisses her forehead, and asks her, "Is it better now?"

"Yes," she says.

Then he asks, "Does it hurt somewhere else?"

"Here," she replies, pointing to her lips.

So the boyfriend kisses her lips. "Is it better now?"

"Much better." "Anywhere else?"

She replies by pointing to her neck. So the boyfriend kisses her neck

Annoyed at the pitiful public display, the elderly man asks the young man, "Excuse me son, do you do hemorrhoids?"
