Number One.
I will not poke Hufflepuff's with spoons, nor will I insist that their house colours indicate that they are "covered in bees".
"WHO DID THIS?"
Professor McGonagall yelled as the Slytherins, Ravenclaws, and Gryffindors all burst out laughing at the sight of the Hufflepuffs all attempting to swat bees away from themselves. A massive swarm of the flying pests had suddenly descended from the magical ceiling, and as the teachers all set about trying to rid the Great Hall of them, they had made straight for the Hufflepuffs. This was clearly someone's idea of a joke, for although the bees themselves didn't harm anybody, the spoons laying in front of each of the Hufflepuffs rose into the air and began jabbing at anyone they could reach, allowing the witches and wizards to believe that they were being stung.
"HELP!"
"I'M ALLERGIC TO BEES!"
"PROFESSOR! HELP!"
Cries of pain and distress could be heard from the Hufflepuffs, while tears of mirth rolled down the faces of the onlookers, not least the Golden Trio or rather… the two. While Ron and Harry laid their heads on the table and banged it with their fists, barely able to breathe, Hermione darted forwards and raised her wand at the same time as McGonagall, Flitwick and Snape, and together, the four of them rid the Great Hall of the bees, and the cutlery fell back to the tables with a clank.
Hermione stalked out, leaving Ron and Harry, still unable to breathe for laughing, to be marched out of the Great Hall by a stony faced Professor McGonagall to explain why exactly it was that they believed it would be humorous to covered the Hufflepuffs in bees and poke them with spoons.
Needless to say, when they returned to the common room, they were heroes.
