MADONNA DOES 'WAYNE'S WORLD'

Although Madonna hasn't guested on NBC's Saturday Night Live since she hosted the 1985-86 season premiere, look for her to return to the show sometime in May. This time out, Madonna will be seen in a dream sequence during a segment of "Wayne's World," a recurring sketch about Wayne (Mike Myers) and Garth (Dana Carvey). two excitable rock-and-roll teenagers who host a cableaccess show from Wayne's basement.

Madonna won't be live though. She filmed the spot recently at the Four Seasons Hotel in Los Angeles. An informed source says a hotel room was transformed into Madonna's bedroom and that she played her scene "comically, as an ultraversion of herself."

As Wayne might put it, "Mega-excellent, Garth."

SAMMY'S STUFF: ON THE BLOCK

Need a Nehru jacket? The personal effects of the late Sammy Davis Jr. will be auctioned off this fall at the Butterfield & Butterfield auction house in Los Angeles.

While the Sammy collection boasts some high-ticket items, including one of Andy Warhol's famous Campbell's Soup-can paintings (valued at $80,000-plus), A Le Roy Neiman painting of Sammy with Bill Cosby and a number of original paintings by Frank Sinatra, hundreds of other items fall into what Butterfield spokeswoman Laura Smissaert calls "less important, more personal stuff."

That includes press clippings, scrapbooks, photos, jewelry and memorabilia, including, would you believe, matching red-clay busts of Sammy and John F. Kennedy, the one-of-a-kind Lorna Luft Thank-You Award for "friendship above and beyond the call of duty," the script from Sammy's 1970 Mod Squad episode, and 19 of Sammy's belt buckles.

The word is that the IRS has a claim against Sammy's estate for $5.2 million. Estate lawyer Herbert Sturman would say only that Sammy's widow, Altovise, and the executors are holding the auction "to raise as much money as possible to pay [Sammy's] creditors."

FEAR & LOATHING & DRINKING ON THE LECTURE TRAIL

Gonzo journalist "Dr." Hunter Thompson lived up to his reputation as a hard drinker during an April 4 lecture at Fort Lewis College in Durango, Colo.

Although drinking is not allowed in campus classrooms, the college got the Durango Liquor Authority to grant Thompson a special-events liquor license for his lecture. According to witnesses, he used the libation privilege liberally.

During his rambling 2½-hour discourse on nothing in particular, Thompson and his companion, a redheaded woman in cowboy boots whom he introduced to the audience of 500 as his "interpreter," consumed the better part of a liter of Chivas Regal scotch. He also arrived 30 minutes late, in a white Lincoln Continental, and displayed a stun gun, which he referred to as his "weapon of choice."

At the end of his lecture, and with more than half the house already gone, Thompson's interpreter stood and faced the remaining students and said, "I just adore him. Isn't he great?"
