What makes me smile and laugh the most, is when I'm in the testing center and taking a test that testing my knowledge of the articulation of certain sounds. I try to be as quiet as possible when I make the sounds and try to figure out the question, but I always get a few people who glance over their shoulder and give me weird looks. It's rather entertaining I must admit!
Last class for articulation and phonology, our teacher taught us how to talk with a lisp. Of course this was so that we could understand how to correct a lisp, but I thought it was pretty funny when my teacher talked for a majority of the remainder of class with a lisp. I love my major! :D
