What Do You Give a Plumber?

Here's my plumber. Isn't he cute? He's really handsomer than this photo shows, and he Never Ever has Plumbers' Butt. Two evenings he spent getting my toilet and sinks straight, and he would not accept any money. This is a karmic debt if I ever saw one. Please give me some input, folks. He's outdoors a lot. Shall I knit him a scarf? He's 6'5" so maybe some nice big socks? He races boats...(Nothing is coming to me from that.) Comments please!
