smoking experiments that went good or bad? Today I tried peanuts.

Today I'm smoking two racks of ribs and I just bought a massive bag of peanuts at Costco to take to the Rockies game and decided to just throw a bowl of peanuts in with the ribs for an hour. Well the result is not good. They didn't pick up a lot of smoke but they did get soft and chewy, not all the way to boiled but it was certainly not an improvement. What other experiments have people tried? Success? Failure?
