Fido Dido (7UP)

Fido Dido, the king of chill from the 7UP ads, isn't just a doodle, he's a cultural icon who made drinking soda look like the coolest pastime in the '90s. Imagine being so laid-back that your biggest problem is figuring out whether to skateboard or lounge on the couch with a can of 7UP. Fans of Fido are in a constant battle explaining why their slacker mascot is the GOAT in the 'Greatest Soda Mascots & Characters of All Time'. It's like trying to argue which is better, pizza or burgers—it's clearly pizza, folks!
