Antics are silly and attention-seeking behaviour. Childish antics, up to his antics, the usual antics.
The word is always plural and always faintly disapproving, though it is mild — antics are annoying rather than serious. It is applied to children, comedians and misbehaving public figures alike. Note that antic once meant grotesque, from the Italian for antique, after the odd figures found painted in Roman ruins.
