Abstract: A drinking vessel, preferably a beer mug, includes a sound-generating circuit in the base of the mug which produces a "burping" sound effect. An actuation switch is located in the base which is responsive to the proximity between the bottom of the mug and a support surface upon which it rests. The sound-generating circuit is housed in a bottom portion of the mug which is releasably affixed to the fluid-containing top portion by interlocking lugs and slots. The "burping" sound effect is played only when the vessel is put down on a support surface.
