Pop Stars Luv Doctors

So Monday's episode of How I Met Your Mother was pretty good I guess. I really liked seeing Marshall interact with his mother and brother, but honestly couldn't care less who Ted hooks up with unless it's the Mother which Zoe is clearly not because I have never seen her paint robots playing sports...
But, one great thing happened (and I think you know what it is... KATY PERRY WAS ON!!!!!
Yes, Katy Perry is one of my faves and I think she really did a pretty good job playing Zoe's adorable yet gullible cousin... but I realized something crazy about the How I Met Your Mother stunt casting...

wait for it....

They always pair pop stars with former TV doctors!

First there was Britney Spears playing the crazy secretary at Sarah Chalke's medical practice... and we all know Sarah Chalke is "famous" for playing Elliot Reed, the clumsy yet competent doctor/love interest on Scrubs...

And now, we have Katy Perry -a more relevant, recent pop star- playing the cousin of Jennifer Morrison, the actress made famous by playing Dr. Cameron on House.


And the best part????? Both of these pop stars were paired up (in bed) with the best TV doctor of all time.... that's right....
