This is up there on the list of simplest songs ever written... but you gotta 
love it. It is in dropped D tuning.

"I really need a cup of coffee, go get me a cup-a-joe"
G|------------------------------------------------------------------------
D|-------------------------------------------------------------------------
A|-------------------------------------------------------------------------
D|-0-----------------0------------------0-----------------0---------1--

Play this riff over and over, gradually picking up the tempo...
(After a certain speed, leave out the D sharp note)


"Black and strong!!!"
G|---------------------------------------------------
D|---------------------------------------------------
A|---------------------------------------------------
D|-1-1-1-1-1-1-1-1-1-1-1-1-1-1-1-1-0----

Repeat the whole thing once and youve got yourself a 45-second song called 
"Cupajoe"...
