Some of the hibachi grill chefs have other antics, such as rolling eggs down their flat cooking tools. Sometimes they flip their tools up in the air and juggle them, making clanging noises on the grill top as part of this routine. When there is fire, sometime they play a train whistle. Sometimes they put the fire out with water and say the firemen have arrived.
Often they start cooking by putting fire on the grill top before any food is on the grill.
Some tell jokes.
