Zack, Sheldon and others in “The Justice League Recombination”

You know, I saw this great thing on the Discovery Channel: turns out that if you kill a starfish, it'll just come back to life.

Was the starfish wearing boxer shorts? Because you might have been watching Nickelodeon.

No. I'm almost sure that it was the Discovery Channel. It was a great show; they also said dolphins might be smarter than people.

They might be smarter than some people. [Sheldon and Raj laugh; Penny is disgusted]

[oblivious] Well, maybe we can do an experiment to find out.

That's easy enough. We'd need a large tank of water, a hoop to jump through, and a bucket of whatever bite-size treats you find tasty.
