Otis Spofford (Ellen & Otis, #2)

Otis Spofford is tops when it comes to teasing. There's nothing Otis likes better than stirring up a little excitement in class. He can make a science project turn out all wrong. Without much effort at all, he can turn a folk dance fiesta into a circus. But nothing gives Otis as much pleasure as teasing Ellen Tebbits. Ellen is so neat and well-behaved--and she never fails to get mad!

Then one day Otis's teasing goes a little too far. The whole class is watching, and Otis can't back down. But now Ellen Tebbits isn't just angry-she's planning something...
