It's a shit song by Busted!
I actually like Mondays, it's usually a tame day because everyone's still recovering from the weekend. Tuesday is when the dread starts, Wednesday is the '**** it' day, Thursday is the 'won't be long now' day, and Friday is a heavy rush to get everything done before the weekend. Saturday is the happy day, Sunday is the relax day and if it's a bank holiday Monday like we get in the U.K. it's like another Sunday!
