It’s only $20 off, but if you were planning on attending Cirque Shanghei Extreme on Navy Pier anyway, it’s better than a sharp stick in the eye – especially since you have a lot of available dates from which to choose.  These shows are always breath-taking; the performers make me feel like a total sludge…well, I am, actually…”Hello, Boot Camp?”

Note that this is a limited quantity deal and they’ve sold quite a few already.  If you have any thoughts about seeing this, don’t wait on grabbing the Groupon.
