I wish I had taken a picture before tossing the thing.
I re-caulked my shower / tub this past weekend, and when I got to the tub spout I realized when I removed the caulk there was a gap around where teh spout met the wall. The gap was filled with glue. Not any kind of silicon caulk, but a thick, hard, yellow GLUE.
This was a twist-on style spout, so it was screwed onto a threaded end of pipe coming out of the wall... but I couldn't see that, because the thing wouldn't BUDGE with all of the glue. I spent almost an hour picking and chipping away at the glue before I was comfortable that the spout was twist-on (there was a hole at the bottom for a set-screw, so I thought it might be a slip-on type) and just kind of brute force unscrewed it (not easy, even after removing a bunch of the glue).
Removing the threaded piece of the pipe and putting on a slip-on spout took ten minutes (after cleanup of all the mistakes of the previous homeowner) and less than ten dollars. Why can't people do things right the first time?
