Don't know if the grass will be greener at Borgata on Dec. 13, but it will be the topic of much conversation--and humor--as Cheech & Chong headline the Big B's Music Box theater.

Tickets for the show by the herb-arrific duo--back together for the first time since Dick Nixon was in the Oval Office--go on sale Saturday. It'll cost you the equivalent of three 1971 ounces ($60) to join in the fun.  To cop the ducats, call (866) 900 4948, or go to www.theborgata.com.

More funny stuff

Tickets also go on sale Saturday for Robin Williams, who returns to Borgata Oct. 24 and 25. Williams is looking for a little more of a financial commitment from those who wish to attend: Tix are $355, $325, $295 and $250. They're available at the above number/Web site. 

More blasts from the past

Also on sale Friday are tickets for Riders On the Storm, the band featuring original Doors members Ray Manzarek (keyboards) and Robbie Krieger (guitar). The group, which will feature Fuel's Brett Scallions taking the late Jim Morrison's place, performs Sept. 27 at the Xanadu room inside Trump Taj Mahal.

Admission is $49 and $39. For tickets, call (800) 736-1420, or go to www.ticketmaster.com.
