The weirdest thing I ever saw was on a trip to Asia. They had huge cruise ships on the local river. One of them clearly service Muslims only. It had that weird devils writing all over it, And creepy shrieking music playing.
Off to one side were all the women covered head to toe in burkahs, about 20 of them.
The men were all in the middle doing some weird line dancing with swords.
Two years ago our cruise ship was parked next to the Scientologist cruise ship (Freewinds). That was pretty weird too.
