some people can walk into a perfectly pleasant evening and make everyone else feel like a guest in their own life. in snl’s “dinner date,” kenan thompson and vanessa bayer are celebrating their anniversary when dwayne johnson’s aggressively overfamiliar old friend arrives with his british girlfriend, played by cecily strong. what should be a private celebration quickly becomes an evening dictated by two people who have absolutely no sense of proportion or boundaries. the brilliance is in the imbalance. the intruders behave as though their arrival automatically gives them ownership of the table, the conversation, and everyone else’s attention. the couple being interrupted keeps trying to accommodate them, even as the situation becomes increasingly absurd.
