"Yesterday morning" and "tomorrow morning" is my favorite example. Several previous Indian coworkers of mine would say "today morning", which always made me smile a bit. It's not an unreasonable phrase to exist, given the others do as well.
But "tomorrow morning" becomes "Morgen früh" which is "tomorrow early" (or "early tomorrow" in English). "Morgen vormittags" ("tomorrow before noon") is also a variation.
