Occasionally I'll use okra, depending on availability and general opinion of those who intend to eat it. Bit of an odd, slimy texture most can't get past.
Had one already that I used to manipulate. Cheers!Edit: Guess Lemmy downscaled it on it's own, so here's a catbox file.
From Rollerball (1975). A favorite I would recommend well above Zardoz.
