 I forgot to go back to your... Sprinkler question. Yeah, sprinkler thing. You asked me about CLR, calcium lime rust, which is a household product. You wanted to know during a break, you asked me, can we clean a sprinkler head out with CLR? Similar to what you do for shower heads and stuff like that. Yeah, I think you can get an old toothbrush, and I think CLR might get rid of that...
