8.8/10. Funniest episode in the show so far. Selina telling Gary to stop looking at her "like a Quaker in a titty bar" alone, and his side-eye at her smoking bumped the episode up a notch in the comedy department. But really, every part of this episode worked. Selina being awkward and tiptoeing around her international kerfuffle in Helsinki was great, and the Finnish prime minster made for a surprisingly excellent foil. Plus, throwing in Dave Foley as a Finnish lech was an odd but funny ingredient in the soup.
At the same time, Mike being stuck and summer camp, and having to enlist Jonah, the butt monkey of the show, to help him deal with this world of math he doesn't understand was a blast. The fact that they accidentally get mixed up in a "what did she know and when did she know it" routine with Kent, Congressman Furlong, and Senator Doyle is the icing on the cake.
But the best part is when those stories collide, and Salina, Amy, Gary, and Dan, talk over each other in one big cacophony, only gradually realizing that they're talking about the boob grab vs. the spy business and reacting in shock with each new reveal. Gary's outrage in particular was pretty adorable. Throw in Dan apologizing over and over again and realizing that it's not see easy to be Mike, no matter how ridiculous his job performance may seem, and you have a winner.
