Some of my favorites:

alias dush="du -smh *|sort -n|tail"
alias hashline="printf "%`tput cols`s"|tr ' ' '#'"
alias dateh='date --help|sed -n "/^ *%%/,/^ *%Z/p"|while read l;
  do date +\ %${l/% */}:\|" |${l/% */}|${l#* }";done|column -s"|" -t'
alias randomfact='wget randomfunfacts.com -O - 2>/dev/null
  | grep \<strong\> | sed "s;^.*<i>\(.*\)</i>.*$;\1;"'
alias webserver='python -m SimpleHTTPServer'
alias memdump='sudo dd if=/dev/mem | cat | strings'

However, take a peek! There are literarily tons of very useful one-liners in there!
