At the mentioning of explosions Mao shot right back up into a sitting position, his eyes going wide, sparkling with excitement as his mouth dropped open. Explosions!! That was the best thing he heard all day! Sometimes he could be so easy to please.
"Boy, do I!" He pumped his fist, his voice imitating one of those kids from those cheesy 50s public service announcements and commercials. Oh man, what could he blow up, what could he blow up...? Maybe his math book! YES. He'd get in loads of trouble, but it'd so be worth it. He could say a dog got it, or blame its destruction on bullies or something. At the moment, he didn't care if he couldn't up with a believable story. He laughed when Gully burst out with that 'KABOOM!' and even clapped a bit to show his appreciation of the other boy's dedication to sound effects.
Mao was far too excited for the teacher's yelling to have any effect on him, he smiled madly the whole while, a fact that only infuriated their keeper all the more. He just couldn't sit still, practically vibrating his whole desk with him impatience. He kept looking over to Gully, grinning fit to split his face.
The second the bell rang and they were allowed out of their seats, Mao literally climbed over the desks and chairs in his way until he made it back to Gully. "I know what I'm exploding!"
