I think that is it bargain mugs.
Maybe I'll give it a test run tonight.
The beauty of it is the TRUE random involved.
I had speakers in my living rioom window, and my daughter's (then 4 yrs old) window.
The zombies groan often enough, but so help me GOD!!! When I put her to bed, the damn living dead had not moaned for almost 2 minutes.
She was asleep, so I just tucked her in, kissed her brow gently, and crept out.
No sooner had I got back to the party, then I had an "OH ****!!" moment.
I was running back to her room (I should have just turned the stereo off) when she ran screaming out to the moans of the undead, lol.
No way it is looped.
