Fooling around? Horsing around? Kidding?

[GeneD]

What word or expression would you use if you had to describe a funny (childish?) behaviour, for instance, when someone cooking Italian food jokingly sings Neapolitan songs or speaks Italian, not properly, just to sound Italian, saying, out of place, all Italian words he knows, proper names included (Bellisimo! Chelentano! Pinnocchio! Bravo!, etc.)? What is he doing while cooking? Fooling around? Horsing around? Kidding? Something else?

Speaking Italian is a physical activity, too! Don't forget about their hands.
