The pipe he returned had two pinholes through the bottom of the bowl ,,,probably a defect in the briar,,,this lets air into the tobacco chamber when trying to draw smoke through the stem. Instead of smoke flowing down through the bowl and out the stem, the air flows from the pinholes (at the bottom) out the stem,,,no smoke. Like trying to suck milk through a perforated straw. Not a dumb question at all,,,
