I’ve done a lot of “phone gags” over the years, especially in the early days of cell-phone introduction. I still do a lot of comic strips that involve a cell phone, but I do not consider them phone gags. A joke about a cell phone is a phone gag; a joke that incidentally includes a cell phone is not a phone gag. The cell phone has become so ubiquitous globally that is difficult to imagine never including one in a comic strip about modern life. The above strip, from this date in 2011, is not a phone gag.
