In dance class we were practising the leap frog. 2 girls asked me to check that the lass acting as the base was in the right position, as the dance teacher had me as their partner for the demonstration and I didn't so much as budge. Before I confirmed that the base was sturdy enough (they weren't even remotely ready), the person doing the jump started running. I yelled at them to stop but too late. The base faceplanted hard into the concrete floor and lost a front tooth, which was later found about 20 metres away. To this day, both girls blame me for the injury for not stopping them...
