What's the difference between a bipolar person and a loft full of lemons?
One's a bit erratic and the other's a bitter attic.
I slept with a lemon once. Now I have lemonaids.
You say "easy peasy lemon squeezy"
... but I prefer "depressed stressed lemon zest."
What did the orange say to the lemon?
"'yello!"
Have you heard the one about the lemon cat?
It was a real sour puss.
