Subject: [HELP] modifying hash

I've got a mental block on refactoring the following,

  # given a hash of arrays,
  hash = { 1=>[:a,:b,:c], 2=>[:d,:e], 3=>[:a,:c] }

  # remove a specified element from the arrays if present
  hash.each{ |k,v| hash[k] = v.delete_if{|e| e==:a} }

  => { 1=>[:b,:c], 2=>[:d,:e], 3=>[:c] }

Isn't there a simpler way to remove the matching
elements?  (Maybe my data structure is just lame?)

Thanks,
