Billy Connolly(I)

Billy's Parkinson's Disease was initially diagnosed under informal circumstances in that he was approached by a doctor in his L.A. hotel lobby after an appearance on Conan O'Brien's show in 2012. After the doctor introduced himself as a fan, he then remarked that Billy's shuffling gait resembled that of someone with the possible early onset of the disease and advised him to get a medical checkup.

I'm now a Doctor of Letters. Most of them Fs and Bs.
