Ben & Jerry's Ice Cream are known for their funny flavor names. When Angelo and Kelly went for an ice cream run, Angelo found an interesting flavor, "Marry Me Mint." At first, she didn't get it, until he took out the ring box and got down on one knee. No word on if the ice cream was any good, but apparently the proposal was.
Speaking of surprises, Schrodinger's Cat (the improv troop, not the thought experiment), were performing a live improv show when a surprised happened. Dixie and Brandon were on stage when Brandon went more off-script than usual. He started telling the story of how he and Dixie actually met. That's when he proposed causing a roaring applause.
