My favorite Google April Fools joke was the announcement of GMail. Over a GB of storage space for free? Come on.
It really did seem like a joke at the time since the only other internet mail for free gave you like 2 MB of space.
The joke is there is neither rational arguments for or against gay marriage.
The joke Netflix categories are a good April Fools prank because it’s just on the edge of believability.
Meet my imaginary friends Fairness, Equality, and Snuffleupagus. They tell me my political positions.

You should get more of your positions from Snuffleupagus and fewer from fairness and equality. The left has shown that fairness and equality tend to promote vitriol and hate towards those who don’t agree; Snuffleupagus meanwhile is a pretty easy going guy.
Isn’t that last guy, Snuffleupagus, an anchor on CBS news now?
Funny how the left’s versions of “fairness” and “equality” always involved people taking things they haven’t earned from people who did.
In re: “The joke is there is neither rational arguments for or against gay marriage.”. that is half right – there is no rational argument in favor of gay marriage. There is, however, a rational argument to be made against it:
