builtin shell-builtin [arguments]
Execute the specified shell builtin, passing it
arguments, and return its exit status. This is
useful when defining a function whose name is the
same as a shell builtin, retaining the functional�
ity of the builtin within the function. The cd
builtin is commonly redefined this way. The return
status is false if shell-builtin is not a shell
builtin command.

eg:
cd () { builtin cd $1; test -n "$DISPLAY" && xttitle $PWD }
test -n will ensure you don't waste clock cycles when not running under X.
Using $PWD rather than `pwd` will run faster. Useful during swapping when
you'd really rather have your root prompt come right back while you try to
regain control of an errant process.
hope that helps.
I've personally found that fancy prompts are usually a liability for a
sysadmin. They are nice when not running as root though...
