Cranial nerves - Sensory, motor and mixed

This mnemonic must have come earlier in this post, but I thought that this subject has numerous mnemonics to it's credit including a lot of obscene ones. For sake of completion, let me include something different.

Remember OOOTTA-FAG-VAH for the cranial nerves in order:
  1. Olfactory
  2. Optic
  3. Occulomotor
  4. Trochlear
  5. Trigeminal
  6. Abducens
  7. Facial
  8. Auditory 
  9. Glossopharangeal
  10. Vagus
  11. Accessory spinal
  12. Hypoglossal 

Notes: To remember the first three OOOs, also remeber LPC (?Little PC) to remember the second letters of OLfactory, OPtic and OCculomotor in that order. Next, the TT - remember 0 & 1 which look like tr0chlear & tr1geminal (0 comes before 1). When somebody asks you which is the 10th cranial nerve, be quick to respond 10 / 2 = 5 = V (Roman) for Vagus
The mnemonics to remember the types of cranial nerves:
Some Say Money Matters, But My Brother Says Big Brains Matter More
S = Sensory, M = Motor, B = Both (sensory + motor)
(The first letters of the sentence gives you the property of each of the cranial nerves in order - So, Olfactory is Sensory, Optic is Sensory, Occulomotor is motor..... and so on)
