She used several stinky things, like feta cheese, onions, coffee beans, chocolate, toothpaste, lemons, blue cheese, sun dried tomatoes, vinegar, tuna etc. It was the funniest thing I ever saw. It was hard for people to believe these were items that they actually eat! My mom kept saying, put your finger in there, taste it! It was gross, but so much fun! The mom-to-be even brought the dirty diapers home to let my brother play! I recommend this game to any and all... The laughs are worth it! And of course, whoever guesses the most smells is the winner. The funniest part is the anticipation of what the next diaper will smell like, because some smells were pleasant while others were absolutely STINKY!!!
