Sorry LF, don't have any "one- or two-liners", but maybe these'll do...

Heard someone sing this when I was in high school & thought it was pretty funny:

This land is my land
This land ain't your land
If you don't get off
I'll blow your head off
I got a shotgun
And you ain't got one...
This land was made for me, not you!

Did a Google to find the author & found this site, which has the rest of the parody (I didn't know there was more), & says it was written by David Pratter.


Then there's this very short one by Keith Donnelly (who is absoloutely *brilliant*; if you ever get a chance to see him live, don't pass it up!)

I'm a bicycle lamp and I've been around
I've covered this road from Guildford to Godalming town
Travellin' light... I'm a travellin' light

Cheers,
