The explosion occurred at the one-story ranch home of Andrew and Patricia Puskas at 182 First Ave. at 8:35 a.m., setting one of the children's hair on fire and blowing a cop over the hood of his patrol car.

Koch: I'd like babies of my own to kiss Mayor Koch yesterday admitted that it can get lonely being a politician without a family, and said he might someday marry and have children.

The gunmen followed actress Sherry Lynn, 45, into the building at Park Ave. and 61st St. about 4:30 p.m., police said.

The gunmen forced their way into the apartment and handcuffed Lynn and Reilly.

While one held a gun on the actress and doorman, the other bandit ransacked the apartment, police said. "I'm fine," Lynn said last night "Thank God we weren't injured seriously, and that's what really counts." One of the bandits was described as in his late 20s, about 5-feet-10, 170 pounds, with brown, hair and a pointed nose, wearing a black fedora, narrow, black pants and a dark jacket The other also was in his late 20s, weighed 150 pounds and wore beige or light clothing, police-said.

"Hi, I'm Ed Koch," says hizzoner in the cartoon's first panel.

In the next, Koch slaps the appleknocker into the mud. And in the third panel, the mayor yells: "And I'm runnin for governor, ya hick!" THE TIMES-RECORD of Troy, which is across the river from Albany, disagreed. It recommended that Koch's media adviser, David Garth, "double his fee for trying to make Koch palatable." Garth was philosophical about the ruckus. Using a favorite saying of former Brooklyn Dodger pitcher Preacher Roe, Garth said: "Some days you eat the bear. Some days the bear eats you.
