The GCW Tour, Buenos Aires & Antarctica: Advice from the Stranger in Front of Me

While wandering the streets today I noticed this guy walking in front of me. Happily I had my camera handy...

Lacking anything better to do, and with the bartender about to bring another drink, let's see how I stack up:

#1 --   Done.
#2 --   Done, but more to go.
#3 --   Nope.
#4 --   On TV, and since the program's been retired that will have to do.
#5 --   Done.
#6 --   I can't juggle with three, and at this point I'm not sure it's worth the effort to learn.
#7 --   Probably.
#8 --   Nope. Fishing has never been my thing, but who knows? Maybe someday.
#9 --   Sadly, no. Not likely to happen, either.
#10 -- Who's Sofi, and shouldn't she be having her own baby?
#11 -- Nope. Ballooning will have to do on this one. 
#12 -- This one I don't understand.
#13 -- Video games count, yes? If so, done.
#14 -- Done (at the zoo).
#15 -- Nope, and at this point, never gonna happen.
#16 -- Ditto.
#17 -- Can't really answer this one without definitions for "change" and "the world." 
#18 -- Done. As a co-worker and I were once discussing, we turned invisible at about 35.
#19 -- Sadly, no.
#20 -- Nope (and, frankly, about the last thing I'd ever aspire to).
#21 -- Done. It sucked.
#22 -- I do believe this is a repeat of #11.
#23 -- There are nine people I know who would say this one's done. 

Just under 50%. I guess I better get on it.
