Everything at once is an apt title.  We start off with Brian and Justin happy.  Then we have Justin gets the hickups then he gets pissed.  I'm still not sure about what?  Justin remembers a little bit about prom night.  He talks to the valet and decides to go to his mom's.  Borrows her car to go to the museum?  So what does Brian do?  He calls Emmett.  Now that was a trip.  Riding in a cop's car, with his red cellphone, though I think he likes Jenn's purple phone better.  The three hour tip - Gilligan's Island?  Thank goodness Daphne knows Justin.  I hope that Emmett manages to find the museum.  Next you through Lindsay in the pot and boil.  A recipe for disaster?
