There are many fine versions of Tag (someone is declared 'it' and has to chase everyone else in the hope of catching one and transferring the status of 'it') from freeze tag to zombie tag but one of my all-time favourites is Dying Fly Tag.
As usual one person is 'it' and chases after the the other players who try their best to avoid being caught. However they have a further line of defence...if the catching player is very close to them they can avoid being tagged by quickly lying flat on their back and frantically waggling their arms and legs in the air: a human dying fly. If they achieve this position before being tagged then the chasing player must redirect their attentions elsewhere. If they are tagged then they become 'it'. For greater verisimilitude the chasing player can wield a plastic fly swat.
As with many of these childish games they are even more fun when played as adults.
