A lad I work with came up with this at work today (apologies for the swearing too):
They've been bought out by the Glazers, they'll be in debt for f*cking years
The Stretford is closing down, it's been flooded by their tears
Tevez f*cking hated them and came to be a blue
Now Rooney wants to be one too
Who the f*ck are Man United, who the f*ck are Man United, who the f*ck are Man United
And the Blues go marching on-on-on
We've been laughing like mad and singing it in the office; been getting some really odd looks!
