Scriabin, you raise a legitimate concern. I agree with you that Chaim has changed his delivery slightly and has in fact become even more professional. Chaim has not changed his views at all though. The slight change is simply due to the fact that Chaim has an Israeli movt now with a great chance of attaining power and becoming prime minister. Chaim probably feels that the shows need to be more serious to give the movt the respect it deserves. Back in the day when the bus accident and brazillia took place, Chaim didn't have a an israeli movt to tend to so he concentrated more on the shvartza issue.
Believe me Scriabin, nobody on this forum is more critical of shvartzas than me. I loved those shows in which Chaim impersonated shvartzas more than anything else. I miss them very much as you do. I personally agree with you and would like Chaim to tell more shvartza stories but at the same time, I understand why he doesn't.
