How to say "Thank You"

My post-op appointment with Dr. McNicoll is tomorrow. I got a realllly great bottle of hand-crafted tequila for him (I never thought I'd say this, but I hope my doctor drinks), but I'm stumped when it comes to the thank you note.

This guy saves lives as a job. Day-in, day-out, save a life, ho-hum. How do you say thank you? AND let's not forget that in the middle of a busy, out-of-town conference, he brought a doctor from another hospital in so I could get my surgery a week earlier!

Because of my arm being out of commission, I can't even bake him a cake. Does anyone have any ideas?
