I like the caption that you have already come up with. Good humour is my cup of tea.

Sometimes I use a few words taken (or 'stolen' perhaps) from the lyrics of a song. Or sometimes I use the lyrics for inspiration, but then make a slight change to a word to add my own twist. No shortage of inspiration for photo titles from lyrics. Some of my photos' titles are rather cryptic - rather than giving the photo's 'story' away in the title, I prefer a title that will make the viewer look and think for even longer, when I can. And I try to limit my titles to three words maximum, or four words tops. Although sometimes I do break my own 'rule' and make it slightly longer again.

Someone I know once called a photo of hers: "No Where To Sit".
If she had a better knowledge of the English language she would have had her title correct, and down to three words in the process: "Nowhere To Sit". (It was a very nice photo of two wet seats in the rain.)
