Here's a joke you can use on your friend. It requires you to be sort of good at improv, and your friend to be up on Hollywood gossip. It goes something like this:
You: "Man, what happened that all of the Celebrities are all dying at the same time? Karl Malden, Michael Jackson, Billy Mays... And the latest is some Hollywood actress just died after she stabbed herself with a knife!"
Him: "Really? Who was it?"
You: "I read about it this morning. I don't quite remember the name. Her first name started with an R.... Something like 'Reese.'"
You: "No, no. With a knife."
Ba-dump bump. Thank you. I'll be here all week. Try the waitress and tip the veal.
