Brilliant, both of you, zonahobo and Dharmabum!!! Here are the first round of Silver B.L.O.B.s for these brave first entries:

To John Hardly for:

Well they pushed and squeezed it up the aisle,
I mean, this pig had SIZE,
It rubbed the seats on either side,
like cords on a fat man's thighs.

To Dharmabum for:

It was alright
For a while
I sat there with a wary smile
But when the flight got rough
This piggy had enough
It was spareribs on the hoof
The worst I'd ever seen
A big pissed off porcine

To zonahobo for:

He bolted to the front, then he spun at the cockpit, building up a little more steam
Running straight for the galley, where those meal leftovers, were piled up like a piggy's dream
Well they pushed and shoved, then they offered in-flight peanuts, and tricked ol porky out the door
But he stopped in the gangway, cutting loose with afterburners, just to even up the score

Way to go, Challenge!rs!!
