Perhaps it had an inkling of what was in store!

Officials in Sydney were left chasing after a male baboon and two female baboons who escaped from the Royal Prince Alfred Hospital where the male was scheduled to have a vasectomy.

Apparently, the baboons had escaped from their transport vehicle when being brought to the hospital for the operation.

“They don’t want him to continue breeding with the small troop he’s in,”

“So in order for him to stay, the decision was taken that he should have a vasectomy.”
The females were there simply “to keep him calm,” he said.

What maddening monkey business! ;)
