Joke: Breathalyzer

Shhaaayyy, buddy¹, what's a 'Breathalyzer'?" asked one drunk to his friend at the next barstool.

"Well, I'd have to say that it's a bag that tells you when you've drunk way too much," answered the equally wasted gent.

"Ah hell, whaddya know? I've been married to one of those for years!"
