'America's Favorite Guest', Bill Murray, Strikes Again

Steubenville, Ohio --Bill Murray, the peripatetic star of Caddyshack, crashed a birthday party for five-year-old Caitlyn Kelly, disrupting the Frozen-themed party and making a room full of kindergartners cry and become belligerent.

Dubbed "America's favorite guest," Murray arrived unannounced during a playing of the hit song "Let it Go." He was immediately pelted with blowouts, plastic horns, and hand clappers depicting Frozen characters such as "Anna," "Elsa the Snow Queen," and "Bulda."

Witnesses said the Ghostbusters star started to make a speech encouraging the children to make the most of their childhood, to play games and draw pictures, and to take chances in their upcoming grade school years. His speech was cut short, however, by the high-pitched wailing of Caitlyn and her girlfriends.

"It was bad," said a still tearful Caitlyn, clutching her mother's leg. "I yelled, 'STOP! Mommy, make the bad man go away!'"

Caitlyn's father, Peter, had run into Murray at the Best Western hotel bar near the Kelly household and convinced the star to "liven things up a bit" at his daughter's birthday party.

"I may have had a few drinks and there was Murray at the bar, so I said, 'Hey, Mr. Caddyshack,' wanna' come to my kid's birthday party,' and he said, like, 'Sure. I'm in.' I told my buddies, 'Bill F***in' Murray's coming to my kid's party.'"

Caitlyn's mother, Paula, was not informed about Murray's surprise visit -- only to expect something "freakin' awesome," she said, rolling her eyes.

"While it was amusing, I wish Peter would have told me first," said Paula, who said she had planned her daughter's now-ruined party for over three months.

Waukesha, Wisconsin -- Sridhar Bakayat's celebration for his acceptance into medical school at the University of Tennessee took an unexpected twist when "America's favorite guest," Bill Murray, showed up unannounced at the Holiday Inn Express hotel to a largely bewildered crowd of jubilant family members, many of whom had flown in from their ancestral village in Hyderabad, India.

"We did not know who this man was," said a confused and upset Kumar Bakayat, father of the medical school enrollee. "I was saying my salutations to my son when this man with long white hair and a black hat bursts in through the 'Congratulations, Sridhar!' banner behind me and starts singing. At first, I thought he was congratulating Sridhar, but he wasn't very good."

According to a waiter familiar with the Hollywood star, Murray assumed the character of the smarmy lounge singer that he had made famous in the Saturday Night Live skits of the 1970s and '80s.

"It was pretty cool," said the waiter, who asked that his name not be used. "He was singing 'Feelings' and really getting into it when one of the Indian dude's grandmothers or something started hitting him."

The Hollywood star made a hasty retreat when he was surrounded by Sridhar's sari-clad grandmothers, aunties and cousins, who were shouting insults and threats at him in Hindi.
