You know you've played too much pokemon when...

[Lord Raven]

Here's a few from Rachel:

When there's a blank TV, and only your mother or father could like it.
When it all of a sudden turns from light to dark right when it turns 6:00 PM.

And one from me:
When you have a GBA attached to a GCN attached to a TV and you never play it.

When other people play on GBAs with no screen on it. Check the Ru/Sa sprite of the gaming kid, and you'll see what I mean.
