Marvin is driving??
Robin tells Barney that Jerry is married so it's not going to happen.
Barney: So what? Marriage is just a piece of paper.

"Why did you pause?!"
His plan is to get then stuck in the elevator and they'll rekindle their relationship.

Barney and James fight over who their mom is getting back together.
<Cue black & white musical number>
*slap fight ensues* "My dad would win in a fight" "No, my dad would win in a fight!"

Bellhop: didn't even know Ted complained about him
Claude: has ink on his hand but it was from saving a reefed squid. (true story)
Marshall finds out Daphne's daughter called her and told her not to show up.
Something about oranges, a speeding ticket, Trekkies, and more oranges.
"Kids, they don't understand logic. Kids understand who shows up"
Barney and James agree to drop the issue. Barney finds a replacement 30 year old Scotch. But he drops it when he sees James's dad making out with Loretta.
Barney: Get your damn hands off my mom!
James: Ger your damn hands on my mom!
Sam Gibbs: One on one off?
Turns out, they got back together after James got reunited with his father.

"I'm going to...wait for it...kill myself"

Billy was going to give the Gretzky to Barney and claim that he got the replacement one for him.
He keeps 200 signed headshots of himself in his trunk.
People kept throwing popcorn at him.
Yesterday: Barney asks him to be his best man. Billy's mom: You can come to Thanksgiving this year!
Billy: I thought if Ted screwed up again, I could be the best man.
Ted tells Barney a lie. Barney: Billy rules, Ted drools. Stinson out!
