Hey. I'm battling with powerpoint. What I need... Is an image that I can't find (and don't know how to create). Don't laugh... But I've included a freehand rendition (small Word document).

Basically... I want a normal curve with chunks cut out of it. I've heard that intelligence works like that (or might work like that) which (might) show that people have some kind of inner deficit or disorder rather than mere normal variation. If someone knows what this kind of curve is called (the curve with chunks cut out of it) that would really help me with google images. Thanks.
