Walkers Crisps

A 2008 entry in the long-running and occasionally amusing strand featuring former footballer Gary Lineker caused offence in some quarters. This pastiche of Cliff Richard's Summer Holiday shows Lineker driving an RML-class AEC Routemaster (with the handbrake still on). While he's enjoying a packet of Walkers crisps he inadvertently deroofs the bus under a low bridge. The resulting outrage led to Walkers apologising and recutting the advert.
In the original version, the registration plate is not seen in its entirety; in slow motion it can be seen that the window pillars upstairs were deliberately weakened to ensure the roof would come off. In the recut version more of the bus is seen, and the registration plate CUV350C (ergo RML2350). Reportedly two buses were used in filming, and one was deroofed.
