Jean Chrétien and Bob Rae are both former leaders of the Liberal Party of Canada. Something else they have in common: They like to choke each other.
Rae later returned the favour, sneaking up on Chrétien at dinner and choking him from behind.
Chrétien and Rae's choking gag is a reference to the famous "Shawinigan Handshake" — when, as prime minister, Chrétien choked an anti-poverty protester who got in his way.
Chrétien never apologized for the incident, and he has made light of it in the years since. Although his actions were deemed "un-prime ministerial" at the time, he was given a pass by the public because a knife-wielding intruder had broken into his home just months earlier. So it wasn't unfathomable that he might be somewhat jumpy.
It's kind of his "thing" now.
And now key members of the Trudeau cabinet — Transport Minister Marc Garneau and Defence Minister Harjit Sajjan — are doing it, too.
