Here is the Shellback initiation on my dad’s ship in 1939, about 32 months later it was becoming one of the most famous ships of WWII.

I think the Navy lost something when they did away with these rites. They were bonding and memorable, and as disgusting as they were, few people were hurt doing it.
Just humiliated, and almost always, even for a Captain becoming a shellback, with a grin.

BWAAAAHAHAHAHA!
That video was awesome! Can you imagine a Japanese sub skipper, peering through his periscope, monitoring his future enemy?
CAPTAIN: Whaaaaaaaaaaaaaat????
XO: What is it, Captain? What do you see?
CAPTAIN: I...I...these people are crazy!
