Conan O’Brien returned to The Tonight Show last night in good shape after hitting his head last week during a stunt that involved Teri Hatcher in some sort of silver outer-space bathing suit. Check it out:

Wow, you can almost hear his head go clunk, can’t you? His best line last night: “I hit my head so hard that for five seconds, I understood the plot of Lost.” This injury preempted his show Friday night.

Glad Conan is okay. I’d ask if you ever hit your head that hard, but that’s just begging for comments, isn’t it? Instead, I’ll ask if you watched, and if you’d ever engage in a triathlon competition with Teri Hatcher — looked odd yet amusing, didn’t it? And Andy Richter’s laugh after showing the accident footage is priceless.
