On Smallville it's been established that Clark's attraction to Lana led to the first manifestation of his heat vision. Now I know Clark isn't supposed to see Lois that way as of yet, but in last night's episode, she's put in the position of giving him a lap dance. Are we expected to believe this doesn't arouse him in the least?
If his heat vision had gone off, it would have made a nice moment to discover he was attracted to Lois, and Lois wouldn't have to go through with the lap dance. That's acceptably motivated and humorous to me.
