Bet if you showed that to some of the younger set they wouldn’t know what kind of exercise machine shadowboy is climbing on, but it doesn’t really matter. It’s one of those “you know you’re old when” kind of things.
For example, a few years ago one of my kids asked me why we say “dial this number” when talking about making a phone call. On the other hand, one of them asked me to “rewind” the music CD that was playing, which makes them old.
I don’t know the original source for that .gif, but I do know that it’s time to fast forward to The Overnight Open Thread.
