I have to agree with Mark on this one! One hit wonders scored Hot 100 #1's all the time! Just a few examples:

Baauer - Harlem Shake
Gotye - Someone that I Used to Know
James Blunt - You're Beautiful
Daniel Powter - Bad Day
Crazy Town - Butterfly
DFL - Laffy Taffy
Omi- Cheerleader

^ That's just a few #1's I can name from this decade and the last! I was big on Billboard, so that's why I'm aware! There's plenty of #1 songs by OHW that date back even further like Los Del Rio's 'Macarena'!
