How to make me giggle like a 14-year-old boy

When talking about certain home improvements in the bathroom, take generous advantage of the caulk/cock homophone, as in "Yeah, I'm gonna give that tub some caulk. Gonna fill all its crevices with my thick, white caulk. It's gonna get all the caulk it can handle, uh-huh. Ima squeeze my caulk out all OVER that tub."

And so forth.
