Let sleeping lionesses lie (on top of you)

(CBS) - Here's a funny joke: What do you do when a full-grown lioness falls asleep on top of you? ABSOLUTELY NOTHING.

This clip comes from feline conservatory Cedar Cove. Per the YouTube description, "Early spring weather is perfect for lounging after a long day of spring cleaning at Cedar Cove. Little lioness Shanta enjoys some down time with senior handler Steve Klein who is arguably as comfortable as concrete."

Comfy as concrete is one way to put it. Another way might be "frozen in terror." But then again, you don't get to be senior handler by being jumpy.
