Clipped, jokey formal ending

The formal ending 습니다 rattled off quickly and spelled to match, which sounds brisk, boyish and comic: I will be back, I will find us something, I will put the coins in. It keeps the deference of the formal style while dropping the solemnity, so it reads as playful rather than careless, and it is associated with soldiers reporting to a superior. Do not use it in writing that has to be serious.

Register: playful formal; military and variety-show flavour
