BEST BET : Comedian Garry Shandling will appear Tuesday through Saturday at the Ice House in Pasadena.

Psssst. . . . Don’t tell anyone you heard it from us, but Garry Shandling will be dropping into the Ice House in Pasadena this week to try out some new material for a possible coming concert tour. It’s all very hush-hush. (The word is, the shy guy hasn’t even told his mother yet.)

Shandling, a 40-year-old, “insecure” comedian, starred in his own series--”It’s Garry Shandling’s Show,” what else?--which aired on Showtime in 1986 and was picked up by the Fox network in 1988.

“It’s Garry Shandling’s Show,” named best comedy series by the Television Critics Assn. in 1987, broke most of the unwritten rules of television. Shandling made frequent asides

to the audience, spied on other characters through a video monitor and pulled stunts like inviting the studio audience onto the set while he went to a baseball game.

Shandling bowed out of the show after last season and is working on new material.

If you catch the show, make Shandling’s day: Tell him his hair looks nice.

Shandling is scheduled to appear Tuesday through Saturday at the Ice House, 24 N. Mentor Ave., Pasadena. The cover charge is $12.50 per person, with a two-drink minimum. Call (818) 577-1894 for reservations and showtimes.
