Carefully and with a sedative.
Vets at a Chicago-area zoo have given check-ups to a pair of big apes, a 250-pound grandma and a six-year-old.
Officials at the Brookfield Zoo say both animals are healthy.
The physicals included heart ultrasounds, chest X-rays and dental exams.
The animals were given sedatives before the check-ups.
The grandma gorilla was in the news 15 years ago.
You may remember the story.
She gently cradled a 3-year-old boy in her arms, after he fell into the gorilla pit.
He was rescued unharmed.
