Neal Caffrey from White Collar. He's a con man because neurotypicals and thus people in general interest him, and he has an outside view of their behaviour. He has learned how they express themselves in big and small ways, using it to his own benefit.
Also, the lying. I absolutely think autistics are able to lie, myself included, but not for long, as seen in the way he quickly tells Peter, or only "twist" his words around the truth.
Then there's the awkwardness. In "Stealing Home" Neal overhears Peter speaking saucily to his wife after a presumed night of "enjoying their marriage", and loses his appetite. He seems relatively traumatised when Peter needs to "sleep" with Sarah for a fake blackmail photo. On the other hand, when Mozzie is caught dating a hacker, and he overhears their post-coital bliss he looks like he's fighting the urge to giggle like a 12 year old. He is 30. And in "Uncontrolled Variables", Neal flirts with a secretary, as part of a mission for the Pink Panthers. When she compliments the "pairing" of the wine, he thinks she is talking about the two of them which would indicate she is moving very fast in their relationship. If that is not textbook "teenager talking to a girl", I don't know what is.
His father, James describes his skill at making forgeries a "gift". Savant, hmm?
Lastly there is the episode "Controlling Interest", a therapist, whom to be fair was trying to manipulate him, calls him "too interesting to be normal".
All in all, it explains the ending of the show perfectly. Autism and PDA go hand in hand, and staying with the FBI does involve demands, and without the anklet, Neal doesn't have a justification for accepting these "demands", this control. Agent Siegel uses his aversion to being controlled by a stranger to "handle him", reassuring him through demonstrations of equal knowledge and flattery; making him feel appreciated
