I'm the...heh!...Build-Up Bot! And I really, really need to s-sneeze-! Can you please heh-help me?

(A Note from Dr. Oswald: To begin, first ask, "Do you want me to turn on your sneezing switch?" If they say yes, proceed. If no, wait a while before trying again. This will keep the system from getting overheated. Thank you for your cooperation.)
