Toronto comedian Jasmeet Singh, aka JusReign, has attracted a sizeable following on Twitter and YouTube with his cross-cultural commentaries.
In the video above, he pulls a prank on unsuspecting folks who don't realize that many Sikhs take offence when others touch their turban with their hands.
This issue has at times created tension between the Indian foreign ministry and security-conscious U.S. officials.
It has also been a concern at British airports, according to a 2011 BBC report.
Singh chose humour to get the point across.
He asked people to point to string on his turban. When they reached to touch it, he pounced.
