Science can be funny...

Neil deGrasse Tyson, acclaimed scientist, author and host of Nova ScienceNOW, appeared Monday night on The Daily Show With John Stewart.

The newest edition of Nova ScienceNOW, airing at 7 Tuesday night on WPT covers such topics as epigenetics (how our environment changes our DNA), a code-filled sculpture on the CIA campus, blood cells in dinosaurs and a prominent mathematician and physicist from Belize.

But, on The Daily Show, deGrasse Tyson and Stewart discussed Earth's connection to Mars, how easy it is to cook pizza on Venus and whether or not deGrasse Tyson stole his necktie from the Museum of Natural History's gift shop. You can watch the segment's video below.
