That being said, here's some of the most emotive expressions ever expressed (by some dude's faces) on the SNES:
Andre Agassi Tennis
Cassie Nova: Cheerful!
Billy Lee: Contemplative...plus pudgy-neck.
And wow, they're really jammed into that screen, aren't they? They really should have drawn that from a little farther away; that way Billy's chin wouldn't be practically touching his collar bone.
Shredder + Fraser = SICKLE: the Brian Blessed laugh!
Restaurant Owner: Happy Sideburns!
Bass Master Classic: Pro Edition
Bob Smithers: shifty-eyed bass-induced smugness!
Al Unser Jr's Road to the Top
Al Unser Jr: mixed emotions: surprised/tickled
California Games II
Hangglider Spectator: thirsty + unhinged lower jaw
Razor Ramon: snear!
Pig Boss: AXE-FLINGING RAGE! / Young Merlin: star-tossing smugness!
Sonic Blastman: Cleft-chinned and grinning!
