"The Young and the Restless" perennial Eric Braeden said Neil Patrick Harris needs "a little spanking" after the "How I Met Your Mother" star called him a "D-Bag" for bailing out on a guest appearance.
"Eric Braeden is a D-Bag," Harris tweeted Friday. "The actor, (Robin's dad) agreed to a cameo, then last night bailed, saying the part wasn't 'substantial' enough."
Braeden appeared in a 2008 episode of the show in which his character tried, in flashbacks, to make his daughter more boyish.
In an interview with TheWrap, Braeden said he had nothing but respect for the cast and crew of the show, but that Harris was unprofessional to criticize him.
