It was original humour, and especially in dark times I appreciate a laugh. It helps with sanity.

He came back on topic right after and continued serious. It didn't hurt the conversation at all in my opinion. Quite the opposite, I will remember the points he made even more.

I hate lame puns and quoting movies, though. That's not my kind of humour. Situational humour is best, and the seriousness of the topic added to it.
