The Big Bang Theory Season 1, Episode 6

The Big Bang Theory Season 5, Episode 5

Breaking Bad Season 5, Episode 14
No visible REACTION.
The Big Bang Theory Season 7, Episode 5
...the success or failure of the date would
be based on the biochemical REACTION...
The Big Bang Theory Season 1, Episode 3
