Old box tvs

We got a new flat screen bedroom tv for Christmas. Great, but the problem is what to do with the old (very heavy) 37 inch box tv it replaced? My husband and I got it onto a dolly where it sat for 2 months, first in the hall and then in the living room. It would not fit into either car to be taken to the dump. Destroying the case would leave the big tube, which is the heavy part. So we set a deadline and finally put it into the big rolling trash can. But it did not fit-the lid was propped open about 12 inches. We'll see.
