How do hamsters fit all that food into their cheeks? This little guy is about to show you.
The clip, from the BBC's new "Pets - Wild at Heart" series, shows the hamster getting X-rayed while dining so you can see exactly where everything goes.
And if that's not crazy enough, the program is narrated by David Tennant, the 10th Doctor on "Doctor Who."
Check out more clips on the show's website.
