Pigs, bears
Headline: Castro meets Pope, promises to start praying and going to church.
This is one of those events that was so wildly improbable it was actually used as a rhetorical impossibility like snowballs in Hell or flying pigs. "Tell you what, asshole. You'll get this job when Castro turns Catholic."
Unfortunately it's not what the rhetorician assumed. This rhetorical impossibility happened BECAUSE another rhetorical impossibility happened first. Castro was able to agree with the Pope because the Pope stopped being Catholic, not because Castro stopped being Communist.
But pigs are still grounded, and bears still shit in the woods. At least as of right now. Wouldn't count on tomorrow.
