“Schrödinger’s cat walks into a bar…” (bar joke)

“A guy walks into a bar…” is a typical form of what has been called the “bar joke.” One popular science joke is:
 
“Schrödinger’s cat walks into a bar ... and doesn’t.”
 
Brian Malow, self-proclaimed as “Earth’s Premier Science Comedian,” created the joke and popularized it in a November 2009 performance video.
   
 
Wikipedia: Schrödinger’s cat
Schrödinger’s cat is a thought experiment, sometimes described as a paradox, devised by Austrian physicist Erwin Schrödinger in 1935. It illustrates what he saw as the problem of the Copenhagen interpretation of quantum mechanics applied to everyday objects. The scenario presents a cat which may be simultaneously both alive and dead, a state known as a quantum superposition, as a result of being linked to a random subatomic event that may or may not occur. The thought experiment is also often featured in theoretical discussions of the interpretations of quantum mechanics. Schrödinger coined the term Verschränkung (entanglement) in the course of developing the thought experiment.
