Motorola - Snake
Motorola’s pair of animal-themed Super Bowl ads by McCann-Erickson in 2000 played to the crowds well.
Here a guy (Jason Jones, later of "The Daily Show With Jon Stewart") gets a snake up his pants leg to demonstrate the value of a quick web search. What could have been vulgar actually clearly demonstrates the web capabilities of the phone.
The other ad finds a cuter reptile falling in love with a new web-enabled mobile phone ("Turtle").
Motorola came back to the Super Bowl in 2006 with the epic (on the geological time scale) "Pebl."
