For Billy, life's really quite grim
and made worse by a teacher of gym
Then he finds a wild hawk
and delivers a talk
but the odds it'll end well are slim.

Yep. It's grim up north.

Aye, an it were 'ardest on t'bairns.

Aye, 'appen.

It might be a baby. It's squealing
It gives you an uneasy feeling
There are slithering things
And a blonde lady sings
Though her skin complaint isn't appealing

The spaceship was slimily messed
Up when a Xenomorph guest
Making its home in
A crewman's abdomen
Quite suddenly burst from his chest.

It bursts from a man's chest, doesn't it? Specifically, John Hurt's (unless this is one of the sequels)

You may be right. But I thought I remembered it bursting from Sigourney Weaver.

Quick check says you're probably right. Weird, I could practically picture the scene with Sigourney. But it's been decades since I've seen it.
