I have a 15 month old doing it and trying to grab the other kids noses or poke their eyes but also mom has long hair and lets the child play with it, they pinch each other's noses or she lets the child poke at her eyes or stick her fingers in her ears at pick up cause she is learning. Well had to tell the mom that too bad the child can't distinguish between it being ok to poke mom but not ok to poke their friends, etc. Mom has since curtailed the "game" and child has stopped doing it to the others.
