Forget a second-screen experience, viewers of “Jimmy Kimmel Live” need a box of Kleenex to enjoy their favorite late-night show these days. Jimmy Kimmel returned to ABC’s airwaves on Monday night, when he had a sidekick even cuter than Guillermo.

“Hi, I’m Jimmy. This is Billy,” Kimmel began last night, holding his young son. “I was out last week — because this guy had heart surgery.”

“But look, he’s fine everybody,” he continued, “he may have pooped but he’s fine.”

“And I want to thank Chris Pratt, Tracee Ellis Ross, Neil Patrick Harris and Melissa McCarthy for filling in for us last week,” Kimmel, who began tearing up at this point, continued. “They each gave a full day of their very busy lives to give me time off and I am very grateful to them for doing that.”

“Daddy cries on TV, but Billy doesn’t — it’s unbelievable,” he quipped.

Kimmel then thanked the doctors and nurses at Children’s Hospital in Los Angeles, where Billy underwent successful heart surgery after being born with a heart defect. Unfortunately, if Congress doesn’t fully fund the Children’s Health Insurance Program (CHIP) fund — which was never a partisan issue in the past — some families won’t be as lucky as the Kimmels.

“Tell them to take a break from tax cuts for a minute and fully fund CHIP — now,” Kimmel concluded. “No more two-week extensions.”
