Magician Calen Morelli pulled a trick on everyone when he made it appear a cop slammed him against a wall in search of a bag of pot ... because the cop is an IMPOSTOR!!!
Calen appeared on TMZ Live Monday and spilled the beans ... the epic video -- which has nearly 8 million views -- is not what it seems.
Yes, the magic is real, but the guy in uniform is not a sworn donut-muncher ... well, at least not one with a badge.
Gotta say ... well done.
