Chris Hemsworth took to Instagram on Monday to share a sweet snap with his son along with some other friends including a rabbit, lizard, budgies and a photobombing chicken.

“A little side hustle I got goin, pet detective,” the 37-year-old joked. “Just returned these animals to its rightful owner. My son. He’s trying to repay with love. I’d prefer cash.”

However, the Thor actor’s brother Luke Hemsworth commented, sharing a detail he noticed in the snap, “Dude your head looks Enormously out of proportion!? Maybe lay off the dairy?”

And he wasn’t the only one, with a number of users agreeing with him.

“First thing I noticed,” one user wrote.

“I wondered why Chris’ body looked to have shrunk,” another added.

“I’m so glad I’m not the only one who thought his head looked huge,” a third wrote.

“Is it just me or does this look like a Chris Hemsworth bobblehead?” someone else wrote.

“I was thinking his head looks distorted and large,” another responded.

Others were confused by why dairy would make his head big with one user writing, “Ah yes, quintessential, milk induced head swell. That’s definitely a thing.”

Some simply thought Luke was jealous of his brother with another user jokingly calling him a “hater”.

Some fans were more drawn to the white chicken photobombing Chris.

“The mohawk chicken is a legend,” one person wrote.

“Love the photobombing chicken,” another added.

“It’s the chicken with the cool hair in the background for me!” a third said.

Chris recently finished shooting Thor: Love and Thunder in Sydney and will soon begin work on Furiosa, the origin story of warrior Furiosa before she teamed up with Mad Max in Fury Road. Furiosa will also be shot in Sydney.
