Devon Werkheiser, Lindsey Shaw and others who used to work on their old Nick show were recording a TikTok Live Monday -- this as the second half of the 'Quiet on Set' doc aired on ID -- and they appeared to be cracking jokes at Drake and others' expense.

One of the jabs Devon and co. dropped while discussing the 'QOS' doc included him impersonating a tyrant, presumably Dan Schneider, saying "give me your holes."

Devon acknowledges right after that they shouldn't joke about the topic -- and DB himself certainly agreed ... taking to X to call him out. Drake quote-tweeted the vid, adding ... "Ned’s Declassless…this is wild…laugh it up guys…laugh it up…”Give me your h*les?!!” Really?!"

Devon does attempt to be serious at one point in his IG Live ... noting that what happened to Drake is terrible -- acknowledging it's crazy it stayed under wraps for as long as it did.

He also says that their set from 'ND' was not in any way like what was described in the doc from child actors who worked under Schneider's reign. Still, he continued to giggle with his old costars ... which didn't sit well with Drake, and definitely not with others online.

It's understandable that the 'Ned's' camp is getting trashed right now ... frankly, what Drake and co. revealed on the doc is extremely serious -- not to mention downright disturbing.

In addition to Drake's abuse at the hands of Brian Peck -- several other former child stars claimed they were mistreated while working at Nick ... and others suggested the showrunners and writers were often attempting to sexualize a lot of the kids in not-so-subtle ways.

There are a lot of sketches and costumes -- not to mention slime gags -- that are resurfacing now that come across as wildly inappropriate ... even though DS has denied wrongdoing.

Nickelodeon commented, saying ... "Though we cannot corroborate or negate allegations of behaviors from productions decades ago, Nickelodeon as a matter of policy investigates all formal complaints as part of our commitment to fostering a safe and professional workplace environment free of harassment or other kinds of inappropriate conduct."

They add, "Our highest priorities are the well-being and best interests not just of our employees, casts and crew, but of all children, and we have adopted numerous safeguards over the years to help ensure we are living up to our own high standards and the expectations of our audience."
