Mother-in-law's dentures

Reena, who hailed from a small town in Punjab, moved to New Delhi to live with her daughter and son-in-law. Since she was not keeping well lately, her daughter suggested she move into their home in the city. She brought along most of her treasured possessions which included a small box with five broken teeth from her dentures.

Once settled in the new environment, she asked her son-in-law, Dev where she could get her dentures mended.

Dev offered, "Give them to me and I'll take them to a dentist."

Reena gave her little box containing the teeth to Dev who took them to a dental lab.

He asked the technician how long it would take to mend the dentures, to which the technician replied, "About an hour."

Dev tells him, "I'll do some shopping and collect the dentures on my way back."

When Dev returns to the lab, the technician hands him a plastic bag and his mother-in-law's little box. He says, "I'm sorry I could only fit five of the teeth to the denture."

"Oh!" exclaims Dev,"and what happened to the sixth one?"

"It's here in the box," answers the technician, showing it to Dev. "Fitting the teeth is easy but it's impossible to fit this peanut."
