Aliens have landed

The aliens have landed
It's distressing but they're here
They piloted their flying saucer
through our atmosphere
They landed like a meteor
engulfed in smoke and flame
Then out they climbed immersed in slime
and burbled as they came

Their hands are greasy tentacles
Their heads are weird machines
Their bodies look like cauliflower
and smell like dead sardines
Their blood is liquid helium
Their eyes are made of granite
Their breath exudes the stench of foods
from some unearthly planet

And if you want to see these
sickly, unattractive creatures,
you'll find them working in your school;
they all got jobs as teachers
