La Brea 

Bubbling, troubled, multitudes wash
Restlessly from ancient depths of slime.
Lives lost in the steaming mists of time
Swell up on a gurgling burbling swash,
Yearning to be free as air, from scum
Churning, loosened from their sludgy slum. 

Arise, antediluvian hosts!
Avaunt forever, primordial ghosts!
