How to make fried green tomatoes
can't find the original joke after 60s searching, so here's a rough reconstruction:
How to make fried green tomatoes
1) Select dark green tomatoes with no blemishes
2) Slice longitudinally into 2cm slabs
3) coat with a mixture of salt, flour and spices
4) deep fry for 2mins in oil at 200degC
5) bury result in back yard and buy a burger. Fried green tomatoes are nasty.

OZYMANDIAS by Percy Bysshe Shelley
OZYMANDIAS
by Percy Bysshe Shelley. via http://en.wikipedia.org/wiki/Ozymandias
I met a traveller from an antique land
Who said: Two vast and trunkless legs of stone
Stand in the desert. Near them, on the sand,
Half sunk, a shattered visage lies, whose frown
And wrinkled lip, and sneer of cold command
Tell that its sculptor well those passions read
Which yet survive, stamped on these lifeless things,
