One client had hills to the east and north and really wanted to get the local PBS station located thirty miles to the east. All the VHF stations came in on an antenna pointed right at the hill to the east, but that PBS station's signal came in strongest from due north! So that's where we pointed the UHF antenna.
Sometimes a good reflection is more useful than the direct signal.
Odd aiming can be helpful if there is multi-path. We think of the polar response of the antenna as being 100% in the front direction and 0% in the rear. There can be side lobes and nulls too. One might be able to improve reception by pointing a null at the multi-path. This is a useful technique in urban areas where there is plenty of signal, and lots of reflections.
