It might not be the finest example of public service broadcasting, but BBC1's new "human Tetris" show, Hole in the Wall, is certainly funny. Well, celebrities being dunked in water always gets a laugh round Monkey's tree anyway. So, here are two clips of stars in the first episode - Strictly Come Dancing's Anton Du Beke and former Blue Peter presenter Zoe Salmon; and former Coronation Street actress Sherrie Hewson - failing to fit into gaps in a moving wall and thus end up in a pool of water. It ain't brain surgery but does raise a chuckle. The show launches on BBC1 this Saturday.
