"I don't think it has anything to do with us; we do the complete opposite," Villanueva said. "I don't think it will hurt our profession, because in our communities, people know us."
Morales said there have been past cases of thieves stealing clown costumes to commit crimes.
"We clowns suffer robberies," Morales said. "The criminals have stolen our vehicles, our costumes, our sound equipment, our makeup, and with these same tools we use to work, they use them to commit robberies."
An estimated 500 clowns from around Mexico and the rest of Latin America gathered Wednesday at the International Clown Meeting and held a 15-minute laugh-a-thon "to demonstrate their opposition to the generalized violence that prevails in our country."
As hard as it might sound to be a clown in a country so riven by crime and violence, the laughing came naturally, Villanueva said.
"We laugh at the very things that hurt us," he said. "It is a very special, very Mexican humor."
