No Fun Mondays

No Fun Mondays (stylized in all caps) is a compilation album of cover songs by Green Day frontman Billie Joe Armstrong, released on November 27, 2020. The project consists of 14 cover songs released during quarantine for the COVID-19 pandemic as part of the "No Fun Mondays" series of songs, in which Armstrong would release a cover song onto the Green Day YouTube channel every so often usually on a Monday as the title suggests.

Recording and release
On March 23, 2020, Billie Joe Armstrong released the first song of the series, "I Think We're Alone Now", on the Green Day YouTube channel, announcing the series at the same time. The description of the video reads "Dear friends.. While we've all been in quarantine I've been reflecting on the things that matter the most in my life. Family, friends and of course music. I recorded a cover of Tommy James and the Shondells "I think we're alone now" in my bedroom. I figure if we have to spend this time in isolation at least we can be alone together. Love BJ." The next week, a cover of "You Can't Put Your Arms Around a Memory" was released and, a week after that, a cover of "Manic Monday" featuring a video appearance from Susanna Hoffs. On October 6, it was announced the series would be released as a 14-track album.

Critical reception
Stephen Thomas Erlewine of AllMusic calls the album "a bit of a lark, unexpected in its energy but not its contents." Clash editor Robin Murray calls it "a real blast"., and Julie River of Punknews.org calls it "a pop-rocking good time." At NME, editor Andrew Trendell says "Armstrong paints a pretty spot-on portrait of what it’s like to be alive in 2020, told through the hidden gems of his record collection and delivered with the heart and energy that you’ve always known him for." Rolling Stone calls the album "a batch of fun covers"
