Rather than say "tower, cessna 1243 ready for take off runway X", I say
"tower, cessna 1234 ready for release runway X". I was cleared for take
off in Santa Barbara in front of a 737 on 1/2 final once because the
tower assumed I had been assigned to the VFR/GA runway. I've also
taken off, and then quickly been asked to maintain VFR because the
controller forget to secure my release.
