TheStranger Thingsstar spoke with ET's Cameron Mathison on the red carpet at the 2018 Screen Actors Guild Awards on Sunday, laughing off last year's moment seen 'round the web. While accepting the award for Outstanding Performance by an Ensemble in a Drama Series, Harbour became "very red faced and very impassioned," by his account, prompting a hilariously bewildered reaction from co-star Winona Ryder.
"OK, look, I'm going to explain that because I've been on the opposite side," he began with a laugh. "I've been at an awards show where I've been behind someone and I will say, it's extremely hard to hear what the person is saying. It echoes in a very strange way."
Harbour even admits that he's a fan of of one particular meme from that moment.
"There is a pizza meme, though, with it going into my mouth," he mused, "which I kinda love." Should the Stranger Things cast take the same award during Sunday's ceremony, Harbour says not to expect a repeat of last year.
"There will be other people giving that, so thankfully I'm off the hook," he said. This year, the 42-year-old actor also scored a solo nomination for Outstanding Performance by a Male Actor in a Drama Series.
"If I win, I do have something very personal that I'd like to say," he teased. "It probably won't be as passionate as last year, but I have something very personal that I would like to say. So, we'll see."
Win or lose, Harbour is most looking forward to spending time with his castmates.
"I think we'll probably just hang out at the Netflix party afterwards," he said. "It was really fun last year because you hang out at the party and we have tons of awards, and they're all sitting at the table, and then we just go dance. I really love this cast more than any cast I've ever worked with, so it's always nice to spend time with them."
