Other Uses For Used Campaign Signs

I was having a problem with a hook on one of our barn doors so I was able to pry the door open with a Charles Jannace sign and it worked perfectly. I then became even more creative and considering I had so many extra signs no one would take from the beginning, I re-shingled my entire barn roof with Charles Jannace signs. I'm told I'll get a good 20 years out of them. Do you have any ideas for these nasty campaign signs?
