Do you mean stand up? As far as I’m aware Jon has only done one stand up special for tv - Jon Stewart Unleavened, for HBO in 1996. You can watch the whole thing here
Searching for ‘Jon Stewart stand up’ on youtube will bring quite a bit of other (often bootlegged) stuff up. You can see his entire set from Baltimore in 2013 here for example. And if you add northeastern to that search most of his routine from Northeastern University in 2008 is up in bits.
I’m pretty sure his snl monologue is available free on hulu too.
Hope that helps! Unleavened is great!
