Ode to Coffee

O! coffee, where art thou
When I need thee now?
In thy many flavoured blends
A hot cup would be godsend.

I cannot keep awake
Without a short coffee-break.
With thy life-giving aroma
Save me from going into a coma.

Java, Colombian or French Roast
Thy every flavour, I will toast.
To the end thy loyal slave
Three cups a day I will always crave.

(Inspired by a very sleepy seminar)
