• Depp made the joke after dangling the dog out of a moving car window, according to Whitney Henriquez.

Johnny Depp once joked about putting the dog he shared with ex-wife Amber Heard in a microwave after he dangled the pet out of the window of a moving car, Heard's sister testified in the former couple's high-profile defamation trial on Wednesday.

Heard's sibling, Whitney Henriquez, told a Virginia court about the alleged microwave comments as she referenced the same alleged incident that Heard testified about when the "Aquaman" actress took the stand in the case earlier this month.

Depp, Heard, and Henriquez were in a car together in March 2013 when Depp dangled the teacup Yorkie out of the window, according to testimony from both Heard and Henriquez.

"At some point, I heard the back window open and Johnny is holding our dog out the window," Henriquez testified at the Fairfax County Circuit Courthouse. "And I froze, I was scared. I just remember thinking I knew how inebriated he was, and the dog was very small."

"I thought if she twitched or he lost her somehow she was just going to go out the window," Henriquez told the court.

Henriquez then said that Depp then brought the dog back into the car "and he was just laughing this really scary, loud like it was almost like a cackle. And then made some joke about putting her in the microwave."

"And that was the joke after that — was putting the dog in the microwave," Henriquez testified.

Heard had testified that the alleged incident said came after Depp consumed large amounts of cocaine and hard liquor throughout the night and repeatedly accused her of infidelity.

"He grabs this teacup Yorkie and holds Boo out of the window of the moving car, and he's howling like an animal while holding the dog out the window," Heard had testified about Depp. "And everyone in the car — I'll never forget it — everyone just froze. No one did anything."

Depp has taken Heard to court for defamation, accusing her of damaging his career with false domestic-violence allegations. Heard also filed a $100 million countersuit against Depp, also accusing him of defamation.
