Steve's wicked idea

Just then, Steve piped up. "Hey, Mr S, I got an idea!".
"Oh! What is it, Steve?".
"I won't speak it out loud, but let me whisper it in your ear!" he said.
Next he walked over to the Asian and whispered something behind his hand.
"What the fuck! You serious!?".
"Yeah! Can do?".
"Yes!" David said reluctantly. "And how long does it take to print that?".
"Fifteen minutes, tops!".

Half an hour later, both boys were standing in front of the closed lab door.
"Dude, now tell me, I'm eager to know, what did you tell him?" Jacob asked.
"Will be a surprise, dude!" Steve replied. Just then, the heavy metal door was unlocked from the inside.
