Thermometer as Size Guide Graphic

We would like a image maybe some what rude!!! as we run an adult webstore and would like to use a therometer image to show our products lenght and some other image to show diameter. I have in mind the cartoon type image of a girl and boy but not together as some products are for boys and some for girls each with a cheeky smile that gets bigger the larger the toy, or the more fill the therometer is. I would like at least three smile sizes maybe more. Please only respond if you can give a sample of your work along a similar line. We would like the file(s) in photoshop so we can fill the therometer as needed depending on the product, or at the very least a version with the bulb fill, small, medium, large, blowing the top off.
