In a blink and you’ll miss it moment of television on Monday night, viewers watching “How I Met Your Mother” saw a familiar face (or hair) in the background. The person was Conan O’Brien, who was seen enjoying a brew and apparently talking up a customer at MacLaren’s when Barney scampers by.
Twitter user Jeremy McGovern nabbed a screencap of his appearance, which you see above, and posted it online.
Series star Neil Patrick Harris let audiences know earlier today that someone was coming, tweeting “Watch the new episode of HIMYM tonight and try to spot the awesomest of dudes randomly hanging out at MacLaren’s. #dontblink”
