(Somewhat of a repost, but I'm a fan of these things.)
I had the same feeling, so I tried it out myself. Inspired by Jonesforth (highly recommended), I wrote an arguably complete Lisp interpreter in a single, heavily commented ARM assembly language file.
Lisp is an obvious target, with its minimal syntax and simple concepts. The first Lisp was written in assembly on a machine with comparable capacity to your laptop keyboard's microcontroller, after all.
