Black Sheep Hit: "One Week," originally intended to simply showcase Ed's freestyle rapping skills. They've recently taken to performing a more stripped-down bluegrass version of the song, which sounds much more in-place with the rest of their catalogue.
For a while they stopped playing "If I Had $1000000" in concert, because they got sick of fans throwing Kraft Dinnernote Kraft Macaroni & Cheese to Americans at them during the song. Now they play the song, but they request that you put your Kraft Dinners in the donation boxes.
Part of the reason Steven Page left the band in 2009 was because he was unhappy with the creative decisions they had been making since Everything To Everyone (keeping all songwriting in-band, allowing the other members to Step Up to the Microphone). His Role-Ending Misdemeanor (see below) was simply the final straw.
Executive Meddling: The two new songs on Disc One: All Their Greatest Hits were susceptible to this: "It's Only Me (The Wizard of Magicland)" had its original title in parenthesis because the label didn't want to market a single with a Non-Appearing Title, and "Thanks That Was Fun" was originally called "One Weaker" before the label vetoed it.
Ed has stated that one of the reasons he was able to write the theme for The Big Bang Theory is because science was one of his favorite subjects in school when he was growing up. He also knows the guys at Rooster Teeth and has helped them out with videos they did to help promote the custom content system for City of Heroes.
He was also Captain Flowers in Red vs. Blue. Hell, the band actually collaborated with Rooster Teeth to record their video for "Odds Are", with Freddie Wong and iJustine also featuring in brief cameos.
A second collab "Did I say that outloud?" can be added to that list.
They decided to cover "Lovers in a Dangerous Time" (their first video and the way they were introduced to Canadians due to the video in heavy rotation on Much Music), because, as they pointed out, they knew Bruce Cockburn's music through Canadian radio and his videos on Video Hits. Anyone who grew up in Ontario in the 1980s, pre-Much Music, probably remembers the show well and is familiar with Canadian Content.
Ed is also a die-hard Pinball fan who regularly attends expos and hangs out on the Pinside.com forums. The music video for "Silverball" — which features nearly a dozen pinball machines — was filmed in Ed's basement with his games.
Role-Ending Misdemeanor: Though he had been seriously considering leaving for some time, getting busted for possession of cocaine (right as the band were promoting a children's album, no less!) proved to be the last straw for both Steven Page and the rest of the band, leading to his departure in 2009.
What Could Have Been: The verses for "One Week" were originally going to have more to do with the chorus, but Ed had trouble writing a rap with the intention of performing it, so he recorded himself freestyling for a few minutes and then wrote down the best parts.
