But Glen Innes' Commonwealth bank staff were dressed up like clowns last Friday to raise money for a serious cause.

The Commonwealth raises money through April for the Clown Doctors, which is a not-for-profit that pays comedians to bring humour to a quarter of a million sick kids a year.

The bank branch was decked out all day Friday April 12.

Bank manager Mandy Crisp said the bank has long-standing history dating back two decades.

"Knowing that we can provide support to Clown Doctors in their effort to bring much needed laughter and fun to sick children means a lot to our staff," she said.

"It's also heart-warming to have our local community get behind the effort as well."
