Not all seniors are into hip-hop (just ask Action Bronson). But the Hip Op-eration Crew from Waiheke Island, New Zealand, who call themselves "the world's oldest hip-hop dance crew," are definite exceptions.
The group, which is made up of 37 dancers between the ages of 65 and 96, is headed to the World Hip-Hop Dance Championship in Las Vegas this weekend.
Crew manager Billie "J Buzz" Jordan first got the seniors of Hip Op-eration together.
"I started off just wanting to get the older people out of their houses and dancing in the street," she told BBC News.
"So I set them up as a flash mob. I went round Waiheke Island in my black van and approached anybody who was 65 years or over and had a pulse."
Back in March, the crew hit the Island's main road for a flash mob performance - check that out below:
And earlier that month, they had their first rehearsal in front of a live audience.
As you can see, one member of the crew is wheelchair-bound.
"When they came and asked me to come, I said 'no I can't move my legs,'" 96-year-old Violet "Granny V" Hollis told BBC. "So she said, 'that doesn't matter, we'll put you in the wheelchair. So I came from the first day."
Granny V isn't the only member of the crew with health problems - the website lists six people who use mobility devices, many people who are deaf, and one member who is legally blind - but it seem to be holding anyone back.
Brenda "BB Rizzell" Long (80) had a triple bypass shortly before she started dancing with Hip Op-eration, and John "Snoop J" Baker (79) says his serious heart problems don't stop him from dancing.
"I've had five heart attacks. Nothing stops me," he said. "I'm actually far too fit to get tired."
