Seamus burst in after seeing Professor Obviouslyabadguyjustkickhimoutofthestory.
"Oh, I say, ah say..." he said snorting - but not into anyone's soup (he's so polite)"Professor Obviouslyabadguyjustkickhimoutofthestory has sat on - a hippo!"
Nobody laughed so he slunked out. That happened every time they sat down.
Suddenly he poked his head through the door and said, "Rum do."
And by that time the author tried to post the reply.
