On late-night Radio 4 is a new sketch show from comedians Dan Antopolski, Tom Craine and Nat Luurtsema.

Jigsaw's most notable characteristic - if indeed it is such a thing - is their brevity. Most of the sketches are very short, which given the fact the show is only 15 minutes long is a sensible move. The average length of the sketches appeared to be around a minute.

With such a format, it's key to try and makes the sketches hit the mark as often as possible; in this first episode most of the sketches didn't quite hit the mark, but when they did they really flied. My personal favourites was just one sketch in, when a couple are having sex; the women then gives her partner some strawberries, unaware of his allergy to them. I also quite liked the technology sketch with music about the "Bandwidth Bandito".

It's hard to sum up such a short show, but there are some gems hidden within this shower of sketches. I';l certainly be tuning in next week.
