a better :delegate method?

So we have;

class Bum
  attr_accessor :pants
  delegate :smelly?, :to => :pants
end

We want to ask;

bum.smelly?

clearly if the bum has pants, then it’s only smelly if the pants are smelly
that’s cool,
but what if the bum has no pants?

>> bum.pants
=> nil

>> bum.smelly?
   NoMethodError: You have a nil object when you didn't expect it!
   The error occurred while evaluating nil.smelly?
     from (__DELEGATION__):2:in `__send__'
     from (__DELEGATION__):2:in `smelly?'
     from (irb):7

this needs to be fixed,
but how?
by default we’d expect it to be nil,
but perhaps we want to assume that actually they’re smelly by default
but what syntax?

delegate :smelly, :to => :pants, :default => true

perhaps?
