can confirm, the Swedish Chef (almost) always has human hands. don’t know why. he’s an anomaly that way.
fun additional bit of trivia: most Live-hand Muppets (that is, ones that have articulated glove hands instead of the hands being moved by rods) are performed with the primary puppeteer doing the head and the left hand while a secondary puppeteer, usually a less experienced one, performs the right hand, a task typically known as ‘right-handing’. (the puppeteers use their dominant hands for the head, so for most of them their remaining hand will be the left. I don’t know if they reverse the process and have people left-handing for left-handed puppeteers.) looks like this:
the Swedish Chef is one of the exceptions to that rule, though, because his skits required a lot more complicated hand movement that needed better coordination, so with him one person would work the head and one would do both hands; they also did that for things a character playing the piano. that added complexity might be why he doesn’t have glove hands, plus the fact that he already looks a lot more human than most Muppets anyway. but I don’t really know.
…that was…probably more information than you wanted. sorry.
