That's why we can't have nice things 

It's a statement a mom or dad would make, while exasperated with their child for having broken some household item. For instance, a mother buys a new small appliance for her kitchen, let's say its a stand mixer. The kids start playing with it and jam something in the blades and burn out the motor. Mom walks in and sees the mess and yells, "See! That's why we can't have nice things!"

It's a comment that is actually an irrational thing to say, but it's funny for that reason. A very "mom/dad" thing they would say in the heat of the moment.

"See! That's why we can't have nice things! Dad just bought this VCR, and you kids put a sandwich in it! Now it's broken!"
