The first joke went well, but the rest went downhill. It was later found out that the joke that went well – "I just sacked my two writers – Copy and Paste" – had been done in 2009 by comedian Jeffrey Ross, about Brad Garrett, at a roast of Joan Rivers. Ross had said, "This guy has two writers, their names are Cut and Paste."
"Well, when I started working here, I asked a scientist the exact same question, and he said it was sixty-five million years old—and that was three years, two months and eighteen days ago." The joke is that the employee fails to understand the scientist's implication of the uncertainty in the age of the fossil and uses false precision.
