As one author has noted, "Generations of biology and medical students have relied on mnemonic (memory-aiding) phrases and ditties, ranging from sublimely silly to the unprintably ribald, to help them remember the cranial nerves..."

large pricks can really ream butts and extra large asses, called yards!"
Utilizing this mnemonic in conjunction with any of the above will result in:
Ol, Op, Oc, Tr, Tr, Ab, Fa, Ve, Gl, Va, Ac, Hy
Mnemonics for the type of nerve
Mnemonics for the type of nerve or its function rely upon the letters S, M and B for sensory, motor or both. The mnemonics to remember the types of cranial nerves can be chosen from: S = Sensory M = Motor B = Both (sensory + motor)
A common mnemonic for the functions of the first through twelfth nerves, is "Some Say Marry Money, But My Brother Says Big Business Makes Money." 
Another common variation of this is "Some Say Marry Money, But My Brother Says Big Brains Matter Most," which appears to be a bowdlerized version of the common "Some Say Marry Money, But My Brother Says Big Breasts Matter Most." "Some Say Marry Money But My Brother Says Bad Business Marrying Money
Silly Superman Made Mortal Brothers Make Bets Since Both Boys Made Money"
Some Say Money Matters, But My Beloved Says Being Beloved Matters More."
Skinny Sluts Make Money But My Brother Says Big Bitches Make More"
Or to include the three Trigeminal branches: Some say money matters, some say brains, my brother says big breasts matter most.
Mnemonics for the foramina
To remember the skull foramina (plural of foramen) from which exit the 12 cranial nerves, the following statements may be used:
Cleaners Only Spray Smelly Stuff Right On Smelly Idiots In J. Jonah Jameson High

for Cribriform plate (Olfactory), Optic canal (Optic), Superior Orbital Fissure (Oculomotor), Superior Orbital Fissure (Trochlear), Superior Orbital Fissure (Trigeminal - Ophthalmic), Foramen Rotundum (Trigeminal - Maxillary), Foramen Ovale (Trigeminal - Mandibular), Superior Orbital Fissure (Abducens), Internal Acoustic Meatus (Facial) Or Stylomastoid Foramen (Facial), Internal Acoustic Meatus (Vestibulocochlear), Jugular Foramen (Glossopharyngeal), Jugular Foramen (Vagus), Jugular Foramen (Accessory), Hypoglossal Canal (Hypoglossal)
Mnemonics for Function
You have one nose, so the olfactory nerve is CN I, and it controls the sense of smell and innervates the nose.
You have two eyes, so the optic nerve is CN II, which functions to produce vision.
You have six abs, so the abducens nerve is CN VI, which abducts the eye.
CN VII: A mnemonic for the names of the five branches of the Facial nerve is To Zanzibar By Motor Car, where the five branches are the Temporal, Zygomatic, Buccal, Mandibular and Cervical branches. OR: Tell Ziggy Bob Marley Called. OR: Tempermental Zebras Brutalize My Cervix or Ten Zebras Buggered My Cat. ORTwo Zebras Bit My Cousin.ORTwo Zombies Bit Miley Cyrus.
The number 8 resembles an ear, so CN VIII, the vestibulocochlear/acoustic nerve is a sensory nerve for hearing.
The number 11 can resemble a pair of arms or shoulders, and CN XI innervates the sternocleidomastoid and trapezius muscles and controls shoulder and neck movements.
The saying The tongue licks the wound is a reminder that when the hypoglossal nerve (CNXII) is damaged, the tongue deviates to the same side of a lesion to the cranial nerve. (eg, if the tongue deviates to the right, the right side of CNXII is damaged).
