| i would be more suprised with different number ;)BTW i am not english, but shouldn't it be "of" then "on"?

| I am a native english speaker, and they got it right. A unicorn has one horn _on_ its head. | 
| <<shouldn't it be "of" then "on"?>>
 nope :)
 
 this would be similar to the glasses are on my face.
 | 
| How's it an easter egg? Just the word "Unicorn" itself means "one horn".<<from Latin _unus_ 'one' and _cornu_ 'horn'>>

 You might be surprised that the Google calculator has this trivia built-in, as it relates to an animal rarely used in serious mathematics, and a fictional one at that :)
 | 
| Why not make it a one-box instead? Then I could get answers to other important questions like "number of horns on a cow", or "number or horns on a '65 Chevrolet". |

| Just as surprising is what comes up when you search for "number of horns on a rhinoceros". |

 Rohit made it :)
 | 
| There was a long Q&A in a forum with the guy behind the calculator, and he talked about quite a few other easter eggs and exotic units added for fun | 
| That was in the somethingawful forums. It was also had good insight into life at Google. Goongles! | 
| Oh, comeon... as if "furlongs per fortnight" _are_ used in serious mathematics. :-D | 
| Thanks Philipp & James
 Philipp for adding it
 James for appreciation

| Why nothing for "number of wheels on a unicycle"? ;) |
