Old people. They're the best.

Mike is about to marry Sue, and in this video, his grandparents offer perhaps the greatest wedding toast of all time. Among their pieces of advice: Be good to each other, help each other financially, and make sure you have food in your Frigidaire.

A little PDA never hurts either, even after 72 years. To the happy couple!
