I propose that April 21st be known as Burtday, and that celebrants take their wildest ties out on the town. Festivities include inviting friends, fighting for the check, tipping the waitstaff generously, and photographing the whole thing, naturally.
Or donate what you would have spent to Rehabilitation Through Photography. But you can still wear the tie, and toast Herbert Keppler, a wonderful man doing wonderful things, and having a simply wonderful time.
