Tap Your Head
Ba Noi taught Linus a little thing that ba nois say to little kids:
Clap your hands and Grandma will give you a cake
If you don’t, Grandma will hit you on the head
Don’t worry: if anyone ever tried to hit Linus on the head, Ba Noi would destroy him! Just to be safe, though, Linus both claps his hands and taps himself on the head. Here’s a little video of him running around the kitchen practicing the tapping part.
