Black Dog lyrics

It's plain to see we're no Jack and Jill
You just want to hide away inside that pill
It's a matter of what you take not what you give
My friend says you live to run and run to live
Chorus...
He's a black dog
He's a white dog
He's a brown dog
Don't answer the call that's fine just act the fool
Just sitting inside, get out of your mind is cool?
Don't matter the cost as long as you have some fun?
My friend has it all, he's happy to run, run, run.
