Hello how may I help you? I am holding a party this weekend and I need some good openers What kind of a party are you throwing? It's a pool party. I want to sound smart. I think an intellectual conversation about extraterrestrial life would be perfect! You mean like talk about life on Mars? Maybe. have any more ideas? I think opening with a knock knock joke is always sure to be a conversation starter! Can you give me an example? Knock knock! Who's there Cow says! Nice.
