We cannot look at Kohanim during duchenin because the Shechinah is there. Giraffe’s have a carotid artery like every other kosher animal. Find it and it may be shechted (I would not attempt this trick at home and one would need a VERY big ladder).
The woman/beard thing I actually have heard, as well as sniffing the havdalah candle after it is extinguished is a segulah for your memory (something I do, but I forget where I heard that…).
We never touch muktzah items on Shabbos for FEAR of moving them. But I also never leaned against a car on Shabbos, either, and I see Yeshivish people do it all the time. They also let their kids ride trikes on Shabbos, something I personally never allowed my kids to do, for chinuch purposes. Go figure.
