There definitely are ones. Back when I worked at a smaller tech company, I had an old co-worker who was solely responsible for running our internal DNS. They periodically created new internal URLs that redirected to Rickrolls and shared hid them in random internal docs.

My favorite was one he gave to our CEO who put it in a PowerPoint without checking it first and he clicked it during a presentation! Everyone was a good sport about it.

Those were good times…
