Hi,
  I think you guys are elitists.  What's wrong with 
Coors Light?

OK, OK.  I'm just jokin'.  Many years ago I tried a 
regular Coors, after hearing so much about Coors beer.
After one taste, I asked the bartender, "Can you pour 
this back into the horse?  It's not done yet."

If I won the Lottery, I'd be strictly drinkin' only 
Pilsner Urquell.

[-Rick-]
PS: I four bottles of Fat Tire in my fridge right now.
