They just happened to be smoking heroin in the bathroom of a Chuck E. Cheese in Costa Mesa.
The two men, Colin Zborowski, 28, and Daniel Lubach, 27, were found smoking in a stall by police.
"Both males were observed in the process of smoking heroin," Lt. Greg Scott told CBS Los Angeles. "Officers were unable to establish if either subject had attempted to sell narcotics to others at the restaurant fun center."
Sgt. Patrick Wessel told the Los Angeles Times that the "knuckleheads" chose to meet their heroin dealer at Chuck E. Cheese.
Zborowski was arrested on suspicion of possession of a narcotic, two drug paraphernalia misdemeanors and for being under the influence of a controlled substance. Lubach was only arrested on suspicion of being under the influence of a controlled substance.
