Full Show shas posted a video of the full episode on youtube. Keanu’s segment is at 15:32 through 29:18 min mark. He stays on stage through the rest of the show so you can see him react to the other guests.
Note: I have made a hard copy of the clip in case this one disappears.
Update: The link on youtube above has been changed to a new one that is now active but I don’t know how long that one willlast. Angel has also posted it on her tumblr page and you can view it there.
