The guys at the always-excellent animation blog Cartoon Brew celebrated their fourth birthday today and dredged up a link from February about the improbable Sponge Bob Square Pants Musical Rectal Thermometer (pictured above, business end presumably at the left).
While a complete assessment of the tuneful device’s impact on the development of human dignity won’t be in for years, it’s safe to say that the price of parental failure to closely read operation instructions just went way up.

I happen to have one of those and have pressed it into service quite successfully without a single glimpse at the operation instructions, thank you very much.
Steve:
I hope you pressed gently.
