Welcome to the real world.
Just the other day, I had the opportunity of looking at an oscilloscope measuring mains power. Yours looks like a nice little sine wave, by comparison. Though it was an electrical machinery lab, so I am not particularly surprised about the distortion.
Don't forget: There's a crapton of equipment, most of it misbehaving (I imagine most wall warts and crummy ATX or similar PSUs seriously distort their own power supply), sharing a common supply generated by a bunch of generators delicately balanced to keep things humming along, fighting steam turbines and variable loads.
All things considered, it's a dammed miracle. And we only notice it when it stops working.
