Tipster Sumeet Shah sends word that PrezBo had a rollicking good time at SEAS’s class day yesterday. Shah sends a photo of PrezBo laughing—real human laughs—at speaker Armen Avanessians’ speech. Says one SEASer of the speech: “Hilarious but uninspiring. The whole speech was nerd jokes… he got a laugh with the phrase ‘1.5-micron CMOS’, as did the random engineer in the crowd who yelled out ‘size doesn’t matter’ right afterward. There was a lot of yelling at the SEAS ceremony, actually.”
