I'm going to confess I do on a regular basis and it is quite an easy mistake to make when you go to put the search in and it starts putting your words at the top of the page instead of the google bar and then you have a brief flash of thought "I'm not on Google cos I'm not searching on the google search bar" so you put google into the top bar thinking that's just internet and it loads and it turns out you just googled google. You've wasted 30 seconds of your life.
