Define 'Perfect Pitch'?

HAHAHAHAHA Dude you make me laugh everytime I live for the cynical thought for the frigging day. I have the signs "Today has been cancelled due to lack of interest." And "Everyone brings joy through this door some when they enter most when they leave." Also I have a picture of a tube of toothpaste and roll of toilet paper with the toilet paper saying you think your job is bad? There are hundreds and I think they are all great if you have any more funny ones, mean is even better, post them so my days will go better. Thanks for the giggle.
