Two small yellow tank engines puff around the Quarry.. they both look identical.. Bill: Hey Ben..

Ben: Yes Bill?

Bill: I've got an idea.. Let's get our drivers to remove our nameplates.. smirks Mischievously..

The drivers of the two engines shrug and remove the nameplates..

Bill: Now nobody will be able to tell us apart!

Ben: Heh! seems like the perfect prank then!

The Two twins puff around.. spooking other engines and just goofing around..
