Did you ever have a cel that is so 
dumb/basic/odd, that you keep considering trying 
to sell it, but always find your self putting it 
back in your album, time and again?  It's not 
that it's so beautiful, or that you're really 
enamored of it, or it was a great snag or 
wishcel - and yet you can't let go of it....

My personal hanger-on:  Ayashi no Ceres, Tooya's 
flying butt....
