Though the film isn't in the same league as the latter (not much is, really), 50 First Dates is notable in that it combines the off-the-wall humor of films like Happy Gilmore and Billy Madison with surprisingly dramatic moments.
As if to jog our own memories with in-jokes, Sandler also references a character�s Happy Gilmore-like golf swing as the most ridiculous he�s ever seen and performs a subdued "hahahaha...shutup" from Billy Madison on a nosey customer.
Some of his earlier works like “Billy Madison” and “Happy Gilmore” were by no means great films but were at least entertaining for the Adam Sandler fan.
His character has no mental deficiency (see The Waterboy or Billy Madison or Little Nicky) and actually seems like a decent guy, even if he does have a habit of having one night stands and creating elaborate ruses to not have to leave his phone number.
In the end, the Sandler fans who rally around Happy Gilmore and Billy Madison will probably be disappointed, but those who bask in the lighter side of The Wedding Singer and Punch-Drunk Love will find a minor treasure.
In the immortal words of a kid from Billy Madison, 50 First Dates is most assuredly “retarded or something.”
