"Okay Barney, this is getting ridiculous! You have to make up your mind here - you can be okay with Robin sleeping with other guys or not." Lily reluctantly reached over the desk to give him back the teddy bear over which they had just had a brief (but violent) tug of war. Barney squeezed it, looking alternatively defiant and vulnerable.
"I just... I can't, Lily! I mean, I sleep with bimbos and she sleeps with... a man who was an inspiration to us all. But... there's no comparison between that and her sleeping with Ted again," Barney whined.
Lily rolled her eyes. "So... say if she and Mitch had gotten serious, you wouldn't have gotten angry?"
Barney snorted. "Please, Lily."
"Okay, so some other guy. Some hot, perfect guy... You wouldn't have been jealous then?"
"Well, maybe," he relented. "But none of them would be Ted - 'blue french horn stealing, trying to make it rain, let's get married and have babies and almost convince Robin to do it the first time they dated' Ted. And what if she gets sucked into that again? There would be nothing I could do about it and I'd just have to watch that happen."
"Well, why don't you do something about it now that they're done sleeping together for good?" Lily felt that they were actually getting somewhere with this conversation for once.
"What? Are you kidding? I don't have to do anything - things are back to the way they were, I'm awesome, and... Feely and I are going to go play laser tag. Later, Aldrin!" And with that, Barney swept out of his office, Lily shaking her head at him.
