There's Many a Slip 99 years old

We see the animator's hand as he draws Jerry (Sid Griffiths?). Jerry is cycling along but the artist hasn't drawn him a bike. Speech bubble comes out: "- Mr. Artist! What about the bike?" A bike is drawn in. Jerry carries on cycling. There is moving landscape behind him. Suddenly a fire engine starts bringing up the rear. Jerry cycles along looking scared. The fire engine chases Jerry.
