There are too few side-profile shots of Steve Martin (and his superior nose) on the internet. Finding the image above led me to this smell-related moment from Planes, Trains, and Automobiles (good viewing choice for the holiday season):
Del (John Candy): I got the seat just where I want it, but I can't reach my feet
to get my shoes off. Neal (Steve Martin): That's just fine. Leave your shoes on. Del: I can't relax if I've got my shoes on. Neal: I don't care to breathe your foot odor. Leave the shoes on. Del: Gee it must be swell being so perfect and odor-free.
