OK, maybe cool is a strong word, I mean parading around in these star trek pajamas might actually get you beaten up in some circles (the smug kid in this pic looks like he's about to receive one if he doesn't stop talking into that tricorder) but if i had seen these at 6 years of age, the first thing out of my mouth would have been "cool"
Isn't odd that the outfits from the first movie looked like pajamas? no? oh, never mind then.
Bonus Toy Feature, the guys at the Megomuseum forums are discussing this weird 70's toy I know little about, the Hal Needham famous stuntman stunt set.
