The art of good sketch comedy is in the timing - not just in how gags are delivered, of course, but in realising that some jokes are best done as one-liners while others can be played out over several minutes before being punctuated with a killer punchline. The four-man sketch group Idiots of Ants are masters of knowing when to end one sketch and get on with another - and that, allied with smart writing and committed performances, makes them leaders in the field.
