Carter Bays and Craig Thomas should have added the word "Boom" to the title of this week's episode "Tick Tick Tick" - because it was dy-no-mite!

The good times started from the opening scene, as Robin and Barney replayed their fade-to-blackout and carried through to the emotional end. What made this episode so special for me, though, was how the great script was equally matched by the acting and how they successfully flip-flopped between two storylines that were at opposite ends of the emotional spectrum. 

I'm not sure how much of a stretch it was for Jason Segel and Josh Radnor to play two stoned guys at a concert, but having just gone to Madison Square Garden last week for a Furthur show, I can honestly say they nailed it. That is, of course, the only reason why, I can attest to that scene's accuracy.

Despite their great sandwich faces, I did fear I was going to end up loathing the repetitive joke about the nacho line, but I burst out laughing after Marshall pointed it out the final time following his argument with Ted. The revelation by Lily that the whole concession recession into oblivion was in reality two minutes long was an amazing twist and was made that much better when we saw the creepy guitar guy was an actual cardboard sign.

Of everything that went down though at Groovapalooza, my favorite moments were when Marshall accidentally leaned over to Lily instead of Ted and later when he screamed at the facial hair fan to fork over some nachos before Lily told him she wanted her own. The latter was another great glimpse at just how scary and aggressive our normally gentle giant Marshall can be when he wants to. He reminded me of Harry from Harry and the Hendersons. 

We saw multiple sides of Barney Stinson tonight as well. While distracted by his thoughts of Robin, he still was able to fire off the amazing line to Nora's father that all there is to him are suits, laser tag and saying "wait for it" a lot. While his answer to Robin's question was not as romantic as Kevin's, it was honest, which for Barney is romantic.  

If that wasn't enough, later on we saw him cleaning up the rose petals he had put out for he and Robin's return to her bedroom. Nora gave him every opportunity to get out of telling the truth, but he tonight the man made the suit as he was unwavering in his honesty. 

Sadly for Barney and "Barbin" fans alike, though, Kevin's answer to Robin's question was pretty darn romantic and when she walked into MacLaren's you just knew he was going to be a few steps behind her. Old Ted said that Barney endured the second that would never end that night as Robin shook her head no to him. I'm sure this was the absolute best Robin has looked all season, too, which couldn't have helped matter. She was a vision in green aboard the Tainted Love Boat, wasn't she?

So, in that final scene at the bar, were we being told that Robin and Barney do not end up together or, like Ted, was I sitting in the wrong booth on that one? Let me know what you all thought and be sure to weigh in on your favorite quotes.
