At 11:45 PM, Megan tells Drake and Josh that they will be on the Dr. Phyllis show the next day after school. Walter or Audrey should have intervened well before Drake and Josh kept everyone awake past 11:00 for a third night in a row and on a school night. The parents are conspicuously absent.
Megan's timing for presenting her brothers tickets to be on a talk show is weird. After two nights of interrupted sleep past 11:00PM, she waits to be awakened on a third night to let them know that she purchased tickets for them to be on a TV talk show the next day after school. If Drake and Josh didn't argue and wake her on the third night, when would she have presented the tickets? As is, it doesn't give Drake and Josh much time to check any scheduling conflicts they might have.
