After coming across a topic on M&M's, I was reminded of a story that I was told awhile back from a pastor.

Him and another pastor were traveling in another country. They came upon a house that they were to stay at for awhile. An elderly woman lived there. They entered but didn't find the lady at first. She called out to them from another room to let them know that she was still getting ready, but she invited them to have something to eat. They found food spread out before them. Looking around for a minute, the other pastor's eye caught sight of a bowl of peanuts that was placed off to the side. He happily picked up the bowl and started to eat. A short time later, the lady came out to greet them. But looking around, she noticed something. "There was a bowl of peanuts here awhile ago, what happened to them?", she asked with widened eyes. "Oh, well you told us to go ahead and eat something and I noticed those peanuts right away and I helped myself. My apologies, were you saving them?", the pastor asked. The woman now bore a mortified look on her face. "You see...I love M&M's...but I'm allergic to peanuts...So I take the M&M's in my mouth, let the chocolate melt, and spit the peanuts out in this bowl.."
