Caught on the Jumbotron

Two characters, usually a man and a woman, are at a big, fancy stadium that's hosting a sporting event. At halftime, they do a kiss-cam or somesuch. It lands on the couple. Oh Crap, they're doing something embarrassing, and it's all up there on the Jumbotron for everyone to watch. Alternatively, they are sitting there completely innocently, but the crowd starts pressuring them to kiss (and, typically, they're not love interests). There's usually a momentary Dull Surprise for the characters in either case.
