The Doctor and Rose (it's gotta be rose, for time-period purposes. –grin- )

Overgrown Drable

TARSI
(Time and Relative Dimension in Igloo)

The doctor and his assistantcrashed back through the TARDIS doors, having been chased off their current location by what looked suspiciously like sticky, blue electrical appliances.
"That was close.." The Doctor pointed out, heading back to his usual place at the control panel to get them off this planet.
"Doctor!" he looked up to answer his current favourite assistant, "I just remembered what the TARDIS reminds me of!"
"Oh?"
"Pingu!"
Of all the things she could have said, he didn't expect that,
"What? Well, why?"
"Because Pingu's igloo was bigger on the inside than the outside. Like the TARDIS."
There was a moment's pause in which the TARDIS rattled audibly into space again.

"Well Rose, obviously pingu's family were of the rare breed of Almighty Time-Penguins!"
She laughed, then turned serious for a moment "..really?"
"No"
