Sing/dance

Play peekaboo

Make random mouth noises

Shake a water bottle in an entertaining way

Sneak in and out of the kitchen dramatically

Pile kitchen utensils on top of each other

Pretend a pair of kitchen tongs are a puppet

Pretend the tongs are a bitey animal

Pretend the tongs are a baby head-measuring device

Toss a tennis ball around with tongs, thereby inventing "tongball"

Show him happy people on a mug (who he then smiles and talks to)
