The best beer anywhere. Has been around since 1755, proving that the guys at Guinness know their shit about beer. Brilliant taste, not the stuff people call beer in America. Every good Irishman has (or should have) drank at least 1 pint of beer. Thank God Guinness came to America during the Irish potato famine, when many Irish natives came to America. Guinness can sometimes can be mistaken for Diet Coke with ice cubes...

Also had the best slogan ever:
"My Goodness, my Guinness!"
Dude 1: "Hey, you want some Budweiser?"
Dude 2: "No way, dude, Budweiser's for pussies."
Dude 1: "Then what d'you want?"
Dude 2: "Guinness."

The drink that inspired the Irish rebellion of 1916. Although that got rid of the English, they've been since coming back to drink it. Turns your shit black! Can also rip the hole of ya on the way out, and may dissolve your bowels! But it's worth it....honest!
Jaysus! I've just shit a black baby elephant after that Guinness last night.
