As if anyone were wondering, Sunday’s SAG Awards showed that actors love to get laughs.

Tina Fey, on accepting the comedy series award for “30 Rock,” received the best response of the night when she thanked Globes co-host Amy Poehler: “I’ve known you since you were pregnant with Lena Dunham.”

Bryan Cranston, winning for his “Breaking Bad” performances, began his acceptance speech by quipping, “It’s good to be bad,” and ending with “Tonight, at least, I’m well-endowed.”

Daniel Day-Lewis, after winning for “Lincoln,” noted that an actor had killed President Lincoln and observed, “Somehow it’s only fitting that every now and then an actor tries to bring him back to life again.”

At the awards afterparty, SAG-AFTRA’s Roberta Reardon said the ceremonies — the first since the two unions merged — had been “fabulous, exceeding my expectations.”

Org’s national exec director David White noted that there tends to be far more dancing at the party than at other Hollywood bashes. “We’re not cool enough to care what other people think,” he added.

The party continued at Sunset Tower Hotel, where the Weinstein Co. celebrated the big win of Jennifer Lawrence, who had recovered from the illness that prevented her from picking up her actress trophy from the Australian Academy of Cinema and Television Arts Intl. Awards on Saturday afternoon at Soho House.
