[plt-scheme] Lambda in a list

Hi!

   I am stuck on a problem.

   I am trying to create a list where two of the elements are lambda 
   expressions? Some thing like "'("an-item" 12 a-lambda-expr 
   another-lambda-expr)". 

   Here is how I am defining it.

	(define a-thing
		(list 
			"an-item" 
			12 
			(lambda (x y) (+ x y))
			(lambda (x y) (- x y))
		)
	)

   What I want to do with this construct is to retrieve the third item
   from a-thing, and the execute it with two arguments. This is 
   obvously not working, could anybody please tell me why?

Best Regards!
