Yeah, this is a pretty minor bit of "badassity", but it's big for me because I have tended to pay professional "handymen" to do this kind of stuff in the past. I caulked our bathtub by myself instead of hiring someone. There was a Groupon offering a "fantastic deal" to have someone come to the house and do it for us for only $150! Yeah, right. I just bought a tube of silicone caulk for a few bucks at Target and did it myself.
I kind of want to go back in time and give myself a few dozen face-punches for not doing this sort of thing earlier. Better late than never, right?
