Red Nose Day traditionally sees people being encouraged to “do something funny for money” in aid of the charity appeal, which supports good causes in the UK and around the world.
Here we take a look back in the Reporter Series archive at photos showing fundraising activities in Dewsbury, Batley and Spen over the years.
BBC One will be broadcasting a three-hour Comic Relief fundraising programme tonight (Friday) at 7pm featuring a host of TV stars and comedians.
