Riddles

Alright guys, there are a lot of fun riddles around so let's test our wit and logic (or lack there of :] ) If you get it right please be kind enough to post another one.  Also don't be that guy that looks it all up online, if your wrong that's fine, just try to figure it out on your own.

Let's start with a good one.

A man is all alone (of all humans) on an island.  He has a gun with one bullet in it and no extra ammo.  Yet he is able to kill a puma and cougar, how is this possible?

The puma and the cougar are the same animal. Those are two names for the "Puma concolor".

yepp your turn

I don't like that answer.

post the next riddle someone, and D, sorry man but that's the answer

ShiViChess is supposed to post the next riddle.

idk if he's going to though...do you have one you'd want to post?

O.K., I'll do one.

A man lives on the 7th floor in an apartment.  When he goes to work, he goes down to the first floor in the elevator.  When he comes back, he uses the elevator to go the the 5th floor and takes the stairs to the 7th floor unless it is raining or if someone else is in the elevator.  Why is this?

i know this oe, but i want to see if others acn solve it first

I know this one to. I don't see how it is possible to deduce.

i got it by guessing when i first heard it, i had all of these crazy hypotheses but then i just said the answer, you expect it to be more

What is it?

i wanna see if anyone else will make a guess first

You guesses? What, so you just, out of the blue said "He's a *****." (censored so as to not give away the answer.)

He's a dummy? :)

yeah i was thinking of way more conviluted answers and when they all didn't work/be the answer i just kinda said the answer in frustration cuz i didn't think it being the actual answer

Seems a funny thing to say under frustration.... unless your against those sort of people?

no it's just that i went with something that wasn't some crazy what if thing, if you know what i mean

He's a vampire?
