where is this quote from I’m so smart it’s almost scary. I guess I'm a child progeny?

I know this quote is from Calvin and Hobbes but i need to find an image of the comic with it. either a direct link to a website with the original comic(best for me) or the date it came out or book it was released in would help as well. i need it for an English project that is due by Friday but i would like to get it out of the way now.
