Betty, Sparky, X-5 and Degill ran to the bank and saw that everyone was on the ground laughing. The customers, the bank tellers, even the security guards were all laughing hysterically.

"Better get an ambulance here." said Betty.

"I'm on it," said Degill, who walked out of the bank.

Betty and her crew walked around the bank looking for clues. They saw that a huge safe was opened. When they went in, they saw that all the money was gone. All that was left were a few dollar bills on the ground. Then they saw the same thing they saw at the museum heist, a huge yellow smiley face on the wall with the words PUT ON A HAPPY FACE! written below it.

When the ambulance took the laughing victims away, Betty and her crew tried to figure out who was responsible for the crimes.

"My guess is that it's some sort of small time crook who armed himself with a tank of n2o," said X-5. Betty and Sparky looked at him like they had no idea what he was talking about. "In other words, laughing gas" said X-5, a bit annoyed.

"I think the guy was armed with a feather duster," said Sparky, "And he used it to tickle everyone until he gave him the loot." The others just gave him a weird look and he said, "At least that's what I think."

As everyone was thinking, Betty saw a security camera on the ceiling. She pointed it to the others and said, "I think we can find out who did it."

Betty and her crew went up to the security office where all the screens for the cameras were. X-5 went the control desk and rewound the tape to before the crime took place.

Betty and her crew watched as everyone was just standing around the bank, when all of a sudden, a man in a court jester hat entered. They watched as he pointed a baton at everyone and shot out some kind of gas that made them fall to the ground and laugh. After he sprayed everyone, he grabbed the keys from one of the guards and used them to unlock the safe. He stuffed all of the money into the duffle bag he had around his shoulder. Before he left, he looked at the camera, smiled and waved.

X-5 hit pause to when the man was waving at the camera so that everyone could get a good look at him.

"You know, he looks strangely familiar," said X-5.

"You're right," said Sparky who stared at the crook's face and then snapped his fingers. "Craters! I know were I've seen him before. He was at the club."

"That's where I've seen him before" said X-5.

"Hold on," said Betty, who was a bit confused, "How do you two know this guy?"

"Me and Sparky went to a comedy club a few days ago right here in Celebra," said X-5, "And he was one of the comedians. His name is Daniel Callaway."

"He wasn't really funny though," said Sparky, "He just said a bunch of really old jokes. Like, what time is it when you have to go the dentist?"

"Tooth-irty!" said Betty, "I heard that joke when I was six."

"Exactly," said Sparky, "He just kept saying all these bad jokes until he was booed off stage. But I don't understand why he's quit comedy and went to stealing."

"That doesn't matter right now," said Betty, "What matters is that we have to catch him before he turns someone else into a giggling fool. And I think I know just how to do it."
