No, I became riveted by this sight:

The distinguished professor had a Hello Kitty! Band-Aid on his leg, just visible above a sock when he crossed his legs.
Therein lies a tale, I am sure.
I considered, and rejected, various ideas for how to work Hello Kitty! into a post-talk conversation with him. One of the better ideas (in my opinion) was to fake a minor injury (perhaps on my leg) and ask him if he had a Band-Aid. An even better idea was convincing a colleague to do this instead of me, but he refused to do it, although admitting to being deeply intrigued.
I suppose I will never know the reason for the Hello Kitty! Band-Aid on the deanly leg. Who knew that Deans could be so mysterious?
