This week's two best lines


My two favorite lines in TV shows this week are both said by the same person. Well, sort of.

One is from Sheldon Cooper, the best character on the best comedy ("Big Bang Theory," 8 p.m. Thursdays, CBS) on TV. The other is by Sherlock Holmes, who is starting a series of three modern-day mystery movies ("Masterpiece Mystery," 9 p.m. Sundays, PBS).

Still, these characters are almost identical -- tall, thin geniuses who observe and understand everything ... except the normal, social functioning of average humans. The lines:

-- "Big Bang" (via the CBS promo): Leonard has the audacity to ask if Sheldon has actually expressed his feelings for Amy Farrah Fowler. Sheldon's response: "No! I'm a physicist, not a hippie."

-- "Sherlock Holmes" (via an advance screener of the terrific opening movie): Someone calls Sherlock a psychopath. His response: "I'm not a psychopath, I'm a high-functioning sociopath. Do your research."
