I think the quick fire gags may come from vaudeville, but for example the way Raj and Howard are acting above, could be from Shakespeare. I think both Sheldon and Howard have a wide expression to their personalities. Where other characters would be more wary, they dare to say what they think. I think this is appealing honesty(and let's face it we live in a world of lies!), even when we may not agree with the sentiment. Sheldon picked up some dubious ideas in Texas, but some just come from his own arrogance.
