MSD

I've done first aid and survival training, plus read up a hell of a lot on it. I'm confident that I can do any of the emergency things well enough to keep someone alive for paramedics, and the survival ones well enough to make it for a few days in whatever comes up. Here are the ones I admittedly cannot do:

Automotive
7. Use a stick welder - I've spot welded, but never had a chance to do "real" welding. I'm the king of soldering, though.

Home
14. Carve a turkey - Technically I can. In fact, I carved the turkey for the family last Thanksgiving, but my results are nowhere near as consistent or nice-looking as when my uncle does it.

Military Know-How
50. Drop and give the perfect pushup - Everyone in my family has a weak upper body (yes, this is our collective fault.) I've never done a pushup in my life, I'm just not capable of it.

Outdoors
55. Tackle steep drops on a mountain bike - I can do biking on trails and roads, but I've never tried steep off-roading. I haven't had a working bike in years. I think I could manage pretty well if I took it slow and had someone to coach me as I learned, but that's not enough to say I could do it.

Teach Your Kids
68. Throw a spiral - Sorry, dad, I still can't do it and it's not your fault. Probably never will with arthritic shoulders.

Technology
80. Ditch your hard drive - I know the proper way, but steel core 7.62 and 5.45 are so much more fun than drilling it.

Master Key Workshop Tools
96. Sand blaster - I've used a bead blaster, does that count?1

Wear eyeliner and offer her shots of absinthe. It's not complicated.
Thanks, Seinfeld.
The hard cider my brother and I made was a huge hit at parties, but I've only tried beer once, in one of those all-in-one kits, and ... let's just say I apologized to my dead homies before I poured the bottles out.
