Underpants Retirement Ceremony

I have a problem. Well, many of them... but I haven't got the time to list them here. The current thing bothering me is that after all that my underpants give to me, I don't have a suitably noble way to send them off. It's a rather poor lifestyle for them. They give so much to me. Then what? In the bin. Well I can't do it. My search for "underpants retirement ceremony" returned zero hits. As did "underpants cremation ceremony". Yes, with quotes included but I didn't do much better without them. So I need suggestions on how to honour the noble underpant and all it has done for me.
