"Cat's Alive!"

Taking the hit. (Scrubs, season one)

Captain Hook. (How I Met Your Mother, "Hooked")

Taking the "metaphorical" leap. (How I Met Your Mother, "The Leap")

These are witty (at least, for me) cliches used in TV shows to remind us/me of the beauty/bitch called love. 

Now, let's add another one: Schroedinger's cat (The Big Bang Theory, "The Tangerine Factor")

Brilliant, just brilliant!
