Go with the Flow

OK so the new President of Earth is a Dolphin alien mutant in disguise. 

The synthetic skin is perfect and except for his high pitched voice  no one would notice anything strange

I should have knocked I suppose, but then I wouldn't have seen him in his pool 

He can't be any worse than the last one and the Earth is mostly ocean, so who better to be in charge.

No Mr President I won't tell anyone so long as you give me that position as agreed, You can rely on my discretion.

Any way, Who would believe me?
