Narrative:

Due to thunderstorms in the area, we were delayed more than 2 hours. We had received our departure clearance. During taxi we were given another clearance to grr with a new squawk due to timing out on the first clearance. We were cleared onto hold on runway 4L. Our takeoff clearance would have turned us into WX. We informed tower that we needed a northerly heading to avoid WX. Tower told us it would be a while before we could get that heading and asked us to exit the runway and proceed to the penalty box. While at the box, we received an ACARS message stating to call the FAA. We queried tower, ground, and dispatch about this message. They did not have any idea who generated the message or what it meant. After the WX cleared, we took the runway again and received clearance for takeoff. After switching to departure, we were asked who we were and where we were going because departure did not have a flight plan on us. We tried to explain what had transpired on the ground but departure was too busy. They switched us over to center. After heading north for several mi, we were ready to turn east and proceed direct to grr. We asked center for this clearance. They were surprised about this request. They were under the assumption that we were heading north to avoid TRSA. We were granted the clearance direct to grr and the rest of the flight was uneventful.
