Here's an oldie...
A newlywed couple is dining at her parent's home with extended family. Two richly-sauced courses in, the groom becomes significantly gassy and really needs to let it loose. Not wishing to embarrass himself, he holds it in.
A moment later, he notices that the parent's dog, Cinder, is sitting beside him, hoping for falling food. Thinking quickly, the groom sees this as an opportunity...he immediately breaks wind. The father-in-law shouts, "CINDER!! WHAT IS WRONG WITH YOU??!!" The groom realizes he can let loose with impunity thanks to Cinder.
The groom uses this as his chance, letting loose from that point forward without hesitation: boom, boom, boom. And with every fart, the FiL exclaims, "CINDER!! WHAT IS WRONG WITH YOU!!??"
This continues throughout the meal, until finally the groom smugly lets out his worst one yet. The FiL exclaims, "CINDER!! WHAT IS WRO G WITH YOU??!! GET AWAY FROM THAT MAN BEFORE HE S****S ALL OVER YOU!!!"
