In case you didn't know - those are code words

Yes Benevolent cucumbersnack was in Amazing Grace

benadryl cumquat is my favorite actor!

Awhile ago a post on tumblr mentioned how if you see someone that you think is on tumblr you say "I like your shoelaces" and they reply with "thanks I stole them from the president" (or something to that effect), basically code for asking if someone uses tumblr

That's cool, but why can't they simply say "are you on tumblr?" "Yeah"

Calvin Harris or Micheal Gambon?

Gambon I think, not sure though

Yes. It's amazing.
