In my opinion, the greatest movie pecs of all time belong to Ricardo Montalban in the movie, "The Wrath of Khan".
This belief holds true even as I consider Arnold
Schwarzenegger in the "The Terminator".
Of course, there are the "no pecs" of SpongeBob and Patrick to reflect on as well.
Oh, forget pecs! What I really love is the bald head of Patrick Stewart as Jean-Luc Picard.
