Coneheads:

In one of the home movie scenes, Beldar looks around to make sure nobody is watching them and then uses his conehead powers to zap the garage door open. However, he and Prymaat and Connie are all in the motorcycle. Just who is filming this and how much did they see?

Prymaat is horrified to see eggplants at the grocery store. But they have lived on Earth for a good twenty years by this point. Hasn't she seen eggplant before?
