Breaks
"Because?" Sherlock repeated, teasingly.
"Because you spoil it for me," John explained. "Now, please, Sherlock, just until the next commercial break, please, keep your deductions to yourself and your mouth shut! Can you do that for me? Please?"
Sherlock rolled his eyes.
"How long is this musical, anyway?"
"2 hours, 38 minutes," John said, curtly, concentrating on the show that had just begun again. "Not including the commercial breaks."
"Alright, let me rephrase my question ..."
"Does it have to be now?" John interrupted, impatiently.
"Just tell me when this whole thing is over!"
"At 5 o'clock," John answered.
"It started at 13:40," Sherlock mused. "If it ends at 17:00 it is 3 hours and 20 minutes."
"Well done, Sherlock, you certainly know your math," John said, sarcastically.
"But you said the running time was only 2 hours and 38 minutes."
"So?"
"So, it doesn't add up."
John inhaled deeply.
"Wait a second," Sherlock added, amazed. "Did I just say 'only'?"
"Yeah, Sherlock, you did, but I would really appreciate it, if you could just be quiet now."
"But it doesn't add up!"
"Sherlock …"
"It doesn't!" Sherlock insisted. "There is a time gap of 42 minutes!"
John sighed.
"Two words for you, Sherlock, and then you shut up, alright?"
Sherlock nodded, reluctantly.
"I mentioned them before," John explained. "Commercial breaks!"
