My most embarrassing moments usually happen when a designer with an encyclopedic knowledge of design / type history asks me if I know something and am totally blank about it. While I am a nerd, I am not the level of nerd that has everyone and everything related to the design / type world memorized, so I find myself in situations a lot where I'm being introduced to THEE famous whomever and I'm like "yeah! I...definitely...know...your work..."
