Google definitely has a sense of humor.
Example 1: I took a moment to clean up my browsing history. I use Google Chrome as my browser . You have to select what you want to delete and how far back. I love that I was choosing what to 'Obliterate' and that I had the choice of deleting items from 'the beginning of time'.
Google also has a sense of humor when you search for ridiculous directions. Ask a silly question, get a silly answer. For example, when I ask how to get to Hawaii from my town here in Oregon, they tell me how. Notice Step 13: Kayak across the Pacific Ocean (2,756miles). Thanks Google!
Do you have other examples of Google being humorous?
