This is a complete and accurate description of every contract I've ever been asked to sign. My apartment lease, my phone bill, etc were all written such that in practice I have no choice but to sign them blindly.

I'm guilty of just clicking through in the general case but I've always read apartment leases. My wife's first apartment she just signed without reading and then when we went to move in together discovered there was no clause in the contract for early termination (apart from the required stuff for Reservists who are called up). The office's stance was quite literally: "sure, you can get out of your lease early - by paying us all the remaining rent or putting your name on this subleasing waitlist and waiting for someone to take your spot."
At the very least, find that part of the leasing contract and read it.
