Fans of the HBO comedy “Curb Your Enthusiasm” know that Larry David can do very little wrong. So it’s a no-brainer that this teaser will leave us all gasping for more. Not only does it give us a healthy helping of Larry David insanity (including, of course, a rolling-on-the-floor physical altercation), but glimpses of appearances be Paul F. Tompkins, Rich Sommer, and Michael J. Fox. Not to mention returning favorites like JB Smoove as Leon and Bob Einstein as Marty Funkhauser. I can’t wait for the new season, and neither should you. Where’s my check from HBO? OK, I’ll settle for free HBO.
