A row of bottles on my shelf
Cause me to analyze myself
One yellow pill I hope to pop
Goes to my heart so it won't stop

A little white one that I take
Goes to my hands so they don't shake
The blue ones that I use a lot
Tell me im happy when im not

The purple one goes to my brain
And tells me that I have no pain
The capsules tell me not to sneeze
Or cough, or choke, or even wheeze

The red ones, smallest of the all
Go to my blood so I won't fall.
The orange one's, oh so big and bright
Stop my leg cramps in the night

Such an array of brilliant pills
Helping to cure all kinds of ill's
But what i'd really like to know
Is what tells each one where to go.
