BLOCKBUSTERS

It's actually about cheese, not the now-defunct media rental store chain.

I've seen things that you wouldn't brie-leve
But usually when I'm asleep, crammed full of cheese

How did this all get inside my mind,
All tough and sharp, like parmesan rind

Some of it really is beyond the pale,
Akin to those fruity veins you get in Wensleydale

In case you missed it, that was puns times one and similies: two
Let them be a warning, just for you

In life you can do as you please
But, before bed
Beware of the cheese
