A a T.A.R.D.I.S.? I thought that was the name of his ship. I only know that because my daughter is obsessed with it.
Rocks are not so cool. The developers of our housing area sold all the top soil and filled it in with rocks (according to my geologist son, the shapes indicate that they should not be there). These guys were Tetris wizards! No portable machine could get through the rocks and 3" Oak roots. I used a hand pick axe to wedge out the rocks. It took 8 days, 8+ hours a day. On the bright side, I separated the rocks by size and plan to use them for future landscaping.
