There is a small bridge just past the Mouth of the Panther, east-southeast of Bravil. Underneath you will find the remains of a Dead Troll. Reminiscent of the children's fairy tale "Billy Goats Gruff", you will find A Poorly Scrawled Note on the body, explaining its failure as a bridge troll:

Mee wurst troll evurr
nobuddy pay brijj tole
me nott sceary enuf
mee gett drunc an kil sellf

Certain shops in the Imperial City are named after restaurants in Maryland, home of Bethesda Softworks. Amongst such are The Main Ingredient and Three Brothers.

As a reference to Julius Caesar, Emporer Uriel Septim spouts numerous quotes from the play itself in the final moments before his death.

In the final Thieve's Guild quest, you're tasked with a seemingly dangerous escape in which the game recommends you equip the Boots of Springheel Jak (enchanted boots provided by the quest that add 50 to your acrobatics). Doing so will protect you from the fall due to a scripted event but the boots are destroyed in the process. However, should your actual acrobatics skill be high enough and/or you have sufficient health, the fall is easily survived without them and you can keep them permanently if you don't equip them before you jump.
