Holy crap! I honestly didn't thnk there'd be another Glen McKenna sighting before the end of the series, but here we are. Season 9, episode 20. Big thanks to my man Matthew Bear for leaving this tip for me in the comments section. This is actually the 4th Glen Mackenna sighting from How I Met Your Mother. You can check out the others here, here, and here. It's a little hard to read the age statement on the bottle (not that it matters considering it doesn't exist anyway) but I'm 99% sure it said 35 years when I watched it on the my big screen.
