Kid running around the living room:

DADDY!!!! DADDY!!!! WHERE ARE YOU?!?! I NEED HELP!!!!

Daddy in basement:
What's going on?

Kid:
IT'S NIGHT TIME AND I CAN'T FIND OUR CAVE!!!!
This is only the beginning :S. In the end, Daddy's help came too late... we got within view of our cave entrance, but got shot down by a few skeletons.

Daddy to Mommy: "Do you remember that place? We once found a cache there!" 
Kid: "I do!" 
Daddy: "How is that possible? We went there before you were born..." 
Kid (matter-of-factly): "I used the TARDIS!" 
Mommy: "He'd sound so dumb to those who don't know what he's talking about..."
Daddy: "But that's a most perfect and logical answer!!!!" :D
