The Big Bang Theory: The Colonization Application Preview Clips Released

CBS has released three preview clips for tonight's episode of the Big Bang Theory, "The Colonization Application."

In the episode, Sheldon applies for a one-way colonization mission to Mars, much to Amy's concern. Maybe Sheldon caught Interstellar, and felt a surge of inspiration?

As the couple debate the merits of deep space travel, Leonard surprises Penny with a rather risque present, and Raj snoops around Emily's apartment--where he is promptly caught. Also, Sheldon and Amy start a family with a pet turtle. Daww.

You can check out the three preview clips below. 

The Big Bang Theory airs Thursdays a 8:00 p.m. on CBS
