It''s No Joke!

SOMEONE''S PLAYING PRACTICAL JOKES -- BUT MEAN MR. DALY ISN''T LAUGHING!

Nancy''s class is going to the zoo on Friday, but first they have to survive a week with their strict substitute teacher, Mr. Daly. And things aren''t looking too good: someone is playing practical jokes on him, and he''s threatening to cancel the trip!

First a sign saying OLD MEANIE is taped to his back. Then someone puts a fake goldfish in his water glass. But who would want to miss a fun trip to the zoo? If Nancy doesn''t find out, the joke will be on the whole class -- and that''s not funny!
