The word Captain is in the shape of an O and there's also a hint in the word My: Abraham Lincoln's picture. This, of course, refers to the poem written by Walt Whitman in 1865 called "O Captain, my Captain."
I gave the hint that you needed to fill in the speech bubbles with what they were saying. The guy who was shivering is saying "Brr". A cat says "Meow" and Homer Simpson says "D'oh" Put them all together and you have "BrrMeowD'oh" in the shape of a triangle. As I count, that would be four puns (for sure three, it actually is a triangle). And the picture of Bermuda in the background should have helped as well. Put everything together and you have the Bermuda Triangle.
Nice picture of the letter J cutting across the street. J-walking is the official name for what he is doing. Is the puppy cute or what?
This one took careful observation before even beginning to figure out the meaning. Looking closely, one can see that the first part of the author's name is missing. Those letters are S T E P. Thus the meaning of the puzzle "Missing a step."
PS I forgot to hit "Publish" last week, so this stayed in my drafts.
