most everything on the triumph dvd has been download-fodder (fodder!) for a few years now. just search for "triumph" on any peer-to-peer network, and you'll get listings for the bon jovi special, the star wars bit, the dog shows, etc.
still, if you're a collector, it'd be a sweet dvd to have.
i actually thought the the conan special / dvd was kinduva 'noying. i mean, the constant barrage of clips were insanely hilarious, but the inbetween set ups and special guests spots were entirely unnecessary. definitely coulda done without'em.
all the same, tho, both dvds are pretty cheap, and probably worth it just to say you have them, and then point and laugh at all of those who dont.
