More Valentine Fun

This is a vintage valentine's card from http://vintageholidaycrafts.com.  This is a type of small card that would be exchanged by children in school.  Many of these cards include puns like this one.

A pun is using words in a way to make an unexpected and funny meaning.   It often uses words that have multiple meanings.

This pun plays with the word popcorn which is the snack pictured.
Another meaning of pop is sudden or unexpected.
Corny means silly or unsophisticated.

Vintage means from the past.  It's a nice way to say something is old and collectible.
