But you can if you go to the Zirka Circus at Dunedin's Princes St Oval over the next week and a-half.
Chinese contortionists Zane Zhang (14), Joey Yang (12) and Charlie Wang (13) dress up as frogs in the circus, and do routines which involve folding themselves up in metal tubes with a diameter no bigger than the size of a dinner plate.
The boys were selected as performers in Zirka Circus after spending up to six years training at the Hebei Acrobat School, near Shijiazhuang, in northern China.
Through a translator, the boys said they loved being in the circus because they were doing what they enjoyed, and they were getting to see the world at the same time.
They are paid for their performances in the circus, and the money they earn is sent back to their parents in China.
But life is not all fun and acrobatics for them. A teacher travels with the circus, and when they are not in the ring, they are in a make-shift classroom doing school work.
While they spent much of the year on the road, they were not homesick because all the circus performers and staff were like family to them, they said.
The trio are among many acts in Zirka Circus, which include the Incredible Double Chinese poles (featuring 10 performers, jumping from pole to pole), Balancing Ballerinas, traditional spinning rugs, juggling, a ridiculous trampoline comedy act, and of course, clowns.
Zirka Circus owner and manager Jeni Hou said her family had been in entertainment and circus for three generations.
She said the present tour showcased an internationally acclaimed cast with unparalleled skill.
''It's two hours of non-stop entertainment, guaranteed to leave you amazed - and there are no [real] animals in sight.''
The circus began at the Princes St Oval in Dunedin yesterday, and will continue until March 26. It will then continue to Mosgiel's A&P Showgrounds from March 30 to April 2.
