That's a good one. My favorite is this one: - F is the 6th letter of the alphabet. - I is the 9th letter of the alphabet. - S is the 19th letter of the alphabet. - H is the 8th letter of the alphabet. 6 + 9 + 19 + 8 = 42. IOW, the dolphins probably manipulated the experiment so that humans would give them more fish.
