"Bubble wrap!" the small dark-haired Doctor exclaimed as he launched himself at the nearest wall.
"Will you please stop popping the walls!" the tall Doctor who was dressed in ruffles and velvet exclaimed in exasperation.
"I can do what I very well please! And, if I want to pop the walls..." the smaller Doctor said, illustrating his point by popping yet another bubble "I will pop the walls."
"Seriously, you can't take him anywhere." the velvet clad Doctor said before attempting to physically remove his predecessor from the immediate vicinity of the wall.
