Although I completely agree with what you've said here in general, the part about the Dalai Lama is a cultural misunderstanding.
"This may not be the norm of your culture, but this is commonly done. After the elder gives a pop kiss and a candy, since there is nothing left in their mouth, nothing left to give, they will say the phrase “Ok, now ‘eat my tongue” (not ‘suck,’ as His Holiness misspoke due to his less proficient English). The Tibetan phrase is “Che le sa”. They say that as in “‘ve given you all my love and the candy so that’s it-all that’s left to do is eat my tongue.” And it is a playful thing that the children know. This is not really done in the Lhasa region (capital of Tibet) so much, but it is more common in the Amdo region (where HH is from). However, it is definitely a Tibetan custom."
