Remember the Google easter egg for searching for do a barrel roll?
Well, it still works. The whole Google search results page will do a barrel roll right in front of you.
The issue is, if you search for just [do a] in Google with Google Instant on, it will show you the search results for [do a barrel roll] and just spin the screen before you can complete your query.
So if you meant to search for [do a hop skip and a jump], good luck because before you know it, the search results will take an unexpected turn.
Here is a video of me replicating the intended issue:
