From Memory Alpha, the free Star Trek reference

Charnock's Comedy Cabaret was a holographic simulation of a 20th century comedy nightclub of Earth, available from the main computer aboard the starship USS Enterprise-D. The simulation includes numerous comedians of Earth history, including The Comic.

In 2365, Data activated this simulation, on the advice of Guinan, to learn about humor. (TNG: "The Outrageous Okona")
