The first time I met hubby's mom, I was sitting in his front room (he was still in high school) and his mom walked in, high as a kite, and said "Hey, girl, do these pants make me look fat??" I had absolutely no idea what to say. I'm happy to say that she has since gone clean and we have a great relationship
The first time hubby met my parents, my mom fixed tostadas for dinner (open faced tacos with crispy shells, in case anyone doesnt know what they are) and he was trying to make a good impression, so he tried using a fork

All of us were digging in with our hands and his plate was a crispy, crumby mess. Ah, memories!!
