I concur with (and won't repeat) XanMag's comments. To offer something unique, here is a bit from my try:
> look at TV
An TV presumably from the 90's, stuck on a newscast.
> turn on TV
> turn off TV
> watch TV
You can't watch a turned off TV
> turn on TV
> watch TV
You watch an adult comedy.
> look at TV

First, it would be useful when your turn the TV on or off to have it give a response. I didn't know it had actually done anything until I tried to watch. Also, I hope you see the disconnect between the "watch" and "look at" responses (unless you're making a social comment by labelling a newscast as "adult comedy").
And it should be "a TV".
