This clip, from NBC's comedy series The Office, is a spoof of Pavlov's original study of classical conditioning.
In the Clip, Jim attempts to replicate Dr. Pavlov's famous study in an office setting. Jim begins by rebooting his computer, causing it to make a bell like noise, every time he does this he offers his coworker Dwight an altoid, which he accepts. Jim repeats this behavior for a few weeks until one day, he reboots his computer and Dwight sticks out his hand, expecting a mint that Jim did not offer. When asked what he was doing, Dwight responded that he didn't know but that his mouth was dry and tasted gross to which Jim laughs in triumph that Pavlov's experiment has tricked Dwight.
In this experiment, Dwight takes the place of the dog in Pavlov's original study. The altoid is the unconditioned stimulus, causing Dwight to salivate and experience a minty taste (unconditioned response). The rebooting computer noise becomes the condition stimulus, causing Dwight to crave an altoid every time he hears it (conditioned response).
Comical television shows, like this one, that reference serious real life scientific work run the risk of offending the scientists whose work they are altering. Some may argue that it is "making fun" of all of the hard work scientists like Pavlov have done. Personally, I feel that references, like this one in The Office, bridges the gap between the laboratory and the average household, creating a link that helps the typical person better understand the concept while making science entertaining.
