Redneck "Spooner" Peril Dept
One reason not to sing absent-mindedly along with Oleta Adams on "Let It Snow, Let It Snow, Let It Snow" when it's 1:15 in the morning and you're concentrating a lot more on your software testing than on your lyrical fidelity:
Because you might announce that you have "brought some porn for copping."
And since Oleta is a very Christian gal I don't think she'd appreciate it the sentiment.
Back to the testing, now. In prudent silence.
