Plumbing
I'm afraid I must once again concede defeat to another plumbing task.

This time it was the kitchen sink which has defeated me so soundly. Although I'm going to get a secret weapon tonight, Sulfuric Acid! I'd like to shake the hand of the clog that can stand up to that! {evil grin with maniacal laugh}

When you do poorly at something, you just have to pull out the big guns to get the job done (maybe that's what everybody else does and they just don't admit it!).

NOTE: Don't put potato skins or bean sprouts down a disposal, those seam to clog things up extremely fast!
