Hundreds packed a New Jersey funeral home Wednesday to remember David Kimowitz, the Manhattan comedy club owner stabbed to death in his suburban home Saturday by the ex-boyfriend of his children’s nanny.

“Looking at this room, at all these faces, I see so many people here to celebrate you, David,” his brother Rich Kimowitz said during funeral services at Bernheim-Apter-Kreitzman Suburban Funeral Chapel in Livingston.

“We’re in shock, but the only way to get through this time is to celebrate the awesome legacy that you created and the amazing cherished memories that every one of us has of you,” he said.

Police have charged Joseph Porter, 27, with murder in the Saturday-morning stabbing that left dead Kimowitz, 40, and the family’s 26-year-old au pair, Karen Bermudez-Rodriguez.

Porter got into the house using a key that he had refused to return to Bermudez-Rodriguez — and allegedly stabbed Kimowitz inside and then chased his ex outside, where police said he stabbed the nanny while she screeched for help.

Kimowitz’s wife, Laura, and two young daughters were away at the Jersey Shore for the weekend when the attack took place.

Rich Kimowitz addressed her directly at the funeral.

“And Laura: Dave loved you so much,” Rich said looking at the front row of the mourners gathered. “You knew him and you gave him what he needed to be Dave.”
