A couple of acts and some jams - why mess with a winning formula? This week's superstars are...

Twinprov! Two improvisers so similar in height you will think they are one person plus a mirror.

Mingle Block! A winning combination of half a dozen players, monologues and pop songs.

Mother's Day! No, not the holiday. Relax. You won't be in trouble for not buying flowers. Although I'm sure this team wouldn't mind some.

Plus, YOU if you put your name in our bucket to take part in two-person scenes and jams.
