def try(*)

@person.try(:children).try(:first).try(:name)
With +try+

@person && @person.children.any? && @person.children.first.name
Without +try+

nil.try(:name) # => nil

It becomes especially helpful when navigating through associations that may return +nil+.
Calling +try+ on +nil+ always returns +nil+. 
def try(*)
  nil
end

def try!(*)

nil.try!(:name) # => nil

Calling +try!+ on +nil+ always returns +nil+. 
def try!(*)
  nil
