Unless You're a Packers WR
According to Wikipedia (WDNL), they are your anterior cruciate ligaments. They are a pair of ligaments in each of your knees.
Your ACL "provides 85% of the restraining force to anterior tibial displacement at 30 degrees and 90 degrees of knee flexion."
Got that?
It connects the femur bone to da tibia bone.
To celebrate (if you can call it that) Test Your ACL Day, you need to twist one or both of your legs at the knee to see how well the ACL holds those bones together.
If something snaps and you can't use your leg properly anymore, you may have discovered the limits of your ACL. (Other wonderful things could have happened too, though.)
If you're an athlete and this happens, your season is done. Go home.

"...the ACL is crucial for stabilizing the knee when turning or planting."
Seriously?
