Looking for card images

[0131]

Hi, i often have the problem that i created a card (currently for CTI 2) but i can't find the best image to represent the card.
I barely had that problem on Classic CTI as i most times created a card for an image i liked.

So this thread is for all card creators who need help to find the best image for their card
Post a description of the card and hopefully the community will help and deliver the perfect image

Here is my first problem, im still creating cards for the Fucked Silly Set and there is this card:

Brain overdrive:
You gained the ability to reduce the effect of any ongoing
Mind State for a short time. The effect always lasts for
the current card and stacks up to 5 times at which it nullifies any effect.
Careful, each time you overuse your brain reduces your IQ by 1.

I would prefer a brain related picture or a picture staring a person (pref. female) thinking realy hard.

Some directions:
example 1 (Too dark)
example 2 (Not thinking hard enough)

... i have a lot more requests but lets do one after another^^

few I found by searching for the "thinking" tag on danbooru, maybe you'll find a few better ones there, or by searching for this tag on other boorus ^^

New request:
I have a Special card which doubles the amount of remaining Questions in the tease.
Text: "Quiz Time!
The amount of remaining questions in this tease is doubled."

I thought rule34 would also cover quiz related topics but looks like its hard to find a good hentai/porn related image incluing a quizshow situation / buzzers or other related stuff.
Maybe you can help me =)
