Thing is...odds are that JR will ALSO be inducted into the HOF this year.

As for why Shatner is inducting the King: back in '90s (can't remember exactly when), William Shatner was a guest on Jerry Lawler's interview segment "The King's Court" (kinda like Piper's Pit.)

Shatner was plugging his new TV series, when Lawler threatened to put Shatner in his place. Shatner then shocked the world by knocking the King flat on his ass.

***EDIT***

Well lo and behold...they actually have the video up on WWE.com!
