What's the Worst That Could Happen?

Both Arizona and Tennessee now allow patrons to carry concealed weapons in bars.  I don't have wildly passionate views on either side of the gun debate, but I'm thinking this might not be the best idea.  Don't worry though, the new law prohibits customers who conceal their weapons from drinking in the bar.  Since nobody under the age of 21 has ever been served alcohol at a bar, either, I'm sure this stipulation will be equally well-enforced.

I might as well go prepare the trauma bay now...
