From 1997 to 2000 Chris Rock had his own show on HBO which was half-talk show and half sketch-comedy, most episodes are available officially or unofficially(only seasons 1 and 2 are on streaming platforms for whatever reason) but three are still missing.
Two episodes of season 3, one featuring Larry Elder(which is partially found online as you can see snippets of Larry and Chris arguing over the Bill Clinton/Monica Lewisnky scandal) and one featuring JB Smoove.
There's also one episode of season 5 missing and that's the most interesting one of the bunch as the guest is none-other than former D.C. Mayor Marion Barry(who Rock notably joked about in several of his routines after Barry was filmed smoking crack).
If anyone has these episodes or knows where I can find them please do let me know.
