What's a funny drinking toast I can say for an end of the world party/my best friend's birthday?

Maybe you can give him a mask party.

The world is certainly experiencing climate change. Deforestation, oil air pollution, and the depletion of drinkable water will all have a devastating result on existence as we all know if we permit it to proceed. The present fiscal situation and the skills give way of the euro zone will also add to the current fears, and worry factors wars. Nuclear struggle would spoil all life on the earth, and there is already ample fear and confusion among the world governments that might be the catalyst for the starting of the tip. In other words, mankind already possesses the vigour to reason his possess extinction. Mankind may have bought knowledge, but mankind hasn't received an equal amount of knowledge and understanding, mankind continues to be at battle with mankind and nature. The chance will not be external in nature, the danger is from within.

How's this?

Drink tonight to the end of the world, tomorrow for surviving it,

Sunday for the hangover, and Monday for Christmas.

"Here's to Rolling Rock" or whatever he prefers

So Amber cool and clear

Not as sweet as woman' lips

But a damned Site more sincere
