Maybe try the balance beam

I love me a small local newspaper. The police log in today's issue of the Warwick Beacon includes this report:

[Name redacted], 21, ... was stopped for doing 50 in a 25 mph zone and for swerving between lanes. Sgt. Bradford Connor said (she) failed a field sobriety test even after she told Connor, “I used to be a gymnast. I can do a cartwheel if you’d like me to.” Connor said he asked her to not do a cartwheel and attempt the heel-to-toe test. She was charged with DWI after she registered a .170 and a .169 blood alcohol level.
