I would remove the toilet first.
Then I would plug the hole that the toilet sets over, it may smell some.
Then I would have a beer and think about that drippy solder.
Then I would get a blow torch and start heating the pipe.
Wait, did I turn off the water yet?
Ok, I'll turn the water off.
That beer is starting to kick in. Darn, now I got the toilet sitting in the yard. Well heck, I can use the yard too. Is that a moose over there looking at me? Never mind moose, just look the other way.
Ok, now I'm using a blow torch, but the water is kind of steaming. Maybe I will cut the pipe and then use the blow torch. Now I'll just take a kleenex and wipe the solder, Damn! that like burns my fingers. Shoulda used a rag I guess. I'll just run some cold water on it.
Hey! Who turned off the water?..........It was me? ........Ok.
Ok, I got the rag, Now I'm wiping the pipe. Seems maybe I should sand it some too. Okay, make it shiny some. What? another beer? Sure.......Why not? How tight do I make this mother? I'm pretty strong, not as strong as the back yard moose, but pretty good. Ungh! Yeah Baby, that's tight.
Shoot, beers kicking in, that moose better be looking the other way.
Okay......done.......grab this toilet and bring it back in. Wax......I should have wax for this. I'll just jump in the snow hopper and run to the store, that will do er. Hey, I'm liking this plumbing. I could do this all day. Do I have enough beer? Better get more while I'm out.
