Let’s just say that for some strange reason, you find yourself in possession of two key pieces of Time Lord technology, the only problem is that both are badly damaged…
The Sonic Screwdriver only has the ability to drive screws…
The TARDIS (an early Type 40 with a damaged Chameleon Circuit, stuck in the form of the classic British Police Box) has lost the ability to travel outside the confines of the Earth, and the time circuits are badly stuffed, so it only has the ability to travel backwards/forwards in time 24 hours at the most, it still has the ability to travel anywhere on the planet, though
How would you use these damaged pieces of Time Lord technology?
Me, as a computer tech, I would find even a damaged “can only drive screws” Sonic Screwdriver incredibly useful, as it still drives screws, I wouldn’t need an entire toolbox of different size/bit configuration screws, it’d make my job a little bit easier, plus, the other techs would envy me, even if they weren’t Who fans…
The damaged TARDIS I would still find useful, I could sleep in as long as I wanted every work day and STILL manage to get to work by 8 AM every day, wake up at 2 or 3 in the afternoon, hop in the TARDIS and show up at work at 8 AM that morning…
Plus, if I wanted a long weekend, I could simply keep going back to Saturday morning at the end of the day
I could also finally travel the world, visit all the places I’d love to see, as well as hang out with my old college friends who now live down in Virginia (I live in Maine), without that horrible 12-14 hour drive to get there
And since the damaged TARDIS is still bigger on the inside, it would also be the ultimate RV/caravan
Basically, I’d treat the hobbled TARDIS as both my car, and my home-away-from-home RV/caravan
