The other ones on here didn't seem right, so I made a lazier alternative without having 
to re-tune every string.

E|---------4---------|   |-------------------|
B|-------6---6---6---|   |-------4---4---4---|
G|-----6-------6---6-|   |-----6---6---6---6-|
D|---4---------------|   |---4---------------|
A|-------------------|   |-------------------|
E|-------------------|x3 |-------------------|

Repeat ad nauseum!
