This only happens when we're (and I do mean all of us, not only a general IT crowd, but people, society as a whole) are too serious about ourselves, up to the level of butt-tight about it. I can't get insulted by the shiny pile, I cant get insulted by the monkey. In best case I'll think its mildly funny and adds some... shine to the presentation, at worst I'll think its simply a lack of good taste and move on with it.
