From Lauren Conrad's blog -- very funny and it does make you feel better after you read/ watch all of the "funnies"
Exploring L2 Language Play as an Aid to SLL: A Case Study of Humour in NS–NNS Interaction. Nancy Bell. Applied Linguistics, 2005. "In the past few years researchers have begun to show an interest in humour and language play as it relates to second language learning (SLL)... Although humour has only recently begun to receive attention from scholars in SLA, it has a history of theoretical and empirical work that dates back to Plato and Aristotle..." Incredibly thorough overview of humor's uses.
We’ve all been told laughter is the best medicine. New studies are showing that laughter can produce similar brain wave patterns as those meditation produces: gamma waves that are associated with the highest state of cognitive processing. Laugh it out!
