Sad Cactus

I haven't blipped in ages, so I thought I'd restart with a pic of the rather sad looking and unfortunately shaped cactus languishing on my green windowsill. I've had this cactus since... well, for a very long time. Well before 2004 so it's at least 10 years old. It probably needs repotting but to be honest it's not looking good. For now I can't bear to throw it out, so it's just sitting there, the butt of all our phallic jokes. Poor Mr. Cactus.
