In the Ultimate Dog Tease, one of You Tube’s most popular videos of 2011 (now almost 94 million views), a man’s voice teases a dog with descriptions of maple-flavoured bacon and other tasty morsels, and the talking dog responds with increasing emotion as each treat goes elsewhere. I chuckle every time I watch, but the clip also reminds me of the importance of teaching because this entertaining conversation is, of course, not conversation at all; it’s an amusing illusion created by brilliant editing.
