4. Gravity:
f, by any chance, you feeling like searching “Google gravity” and hitting “I’m feeling lucky”, don’t be surprised if Google comes crashing down around you the second you move the mouse. (Hint: you can disable Google’s instant results in your account preferences page to make sure you get the ‘I’m feeling lucky’ option)
5. Recursion:
Google pokes fun at its own “did you mean” suggestions if you search recursion (repetition or returning) by questioning your spelling even though you didn’t make a mistake
