My Life as a Toasted Time Traveler by Bill Myers

(The Incredible Worlds of Wally McDoogle #10)

What could be more hilarious than one Wally McDoogle?

How about two? Or Six? Or a dozen?!

Wally travels back from the future to warn himself of an upcoming accident. But it takes more than one visit to get the message across. Before he knew it, there are more Wally's running around than even Wally can handle.

Catastrophes reach an all-time high as Wally tries to out think God and rewrite history.
