Once, during a break in filming Only Fools and Horses,
David Jason and
Nicholas Lyndhurst brought a bag full of bangers into rehearsals; they loaded the stacked chairs with them and the cubicle doors in the toilets. When production assistant Dow unstacked the chairs, they went off, making him afraid to touch them. Jason and Lyndhurst thought it funny until a cleaning lady tried to mop the gents and nearly died of fright. They never pulled that prank again.
