Mutt mistake
“Rover” guided users through Bob's features in ways that the video hopefully shows were clearly re-used once Clippy appeared in the Office suite.
Rover the Useless Pooch was featured in Windows XP search window.
Office 97 had altogether different flea bag: Power Pup, The Caped Mongrel.
Both equally useless, but the Office assistants were WAY more infuriating.
