A future as a plumber

Our sprinkler system has been leaking for a while.  Andrew has tried to fix it, but he needed a little help.

"Yeah, I see your problem"

"There's a ton of water in here."

"Let me try blowing the line out."

"Can I get a hand here?  And bring a thing-a-ma-bobby."

"Yeah, right there. Turn it. No, turn it the other way.  No, the other way." 

"Here, let me do it.  Aaaand there we go.  Done."

"Good as new."
