Unprepared:
The monster's chasing Shaggy and Scooby and they enter a room. Just as the monster's about to enter… "Wait, like, we're not ready," says Shaggy. The monster closes the door. "This never happens, Scoob!"
"It's unprofessional of us," says Scooby.
"Like, we better hurry, that monster's out there waiting and we haven't gotten anything yet!"
"These pants feel funny," says Scooby.
"Those are mine," says Shaggy. The monster gets annoyed and leaves. "Okay, we're ready!" The door opens and they're clowns, but they see the monster's missing. "Can you believe that?"
"How rude," says Scooby.
