(hope it works just by clicking watch, it does for me, but if anyone has issues, check if you have programs or settings that are blocking pop-ups, since the video window pops open as a new window.)
ps. i used both the subliminal message (Jingle Bells Reversed) clip & this Ghostly Car Ad clip to spook my husband when he came home.... he didnt freak like i did, but they made him jump a bit! *hehehehe*
