A co-worker muttered the word "asshole" QUIETLY under his breath to a passing motorist whilst driving with his two daughters recently. Shortly afterwords, his daughter asked him "Why's that man an ash-hole, daddy?"

While playing around with my nephew, I instructed him to tell my brother-in-law "the eagle has landed." He ran to my b-in-law, repeated the phrase, then asked to see the eagle. This continued for a while cause the kid REALLY wanted to see the eagle.

Another co-worker's son is bilingual and can speak to his mother in her native tongue, turn, and speak the same phrase immediately to dad in English without batting an eye. This flips me out since I come from the barely mono-lingual South.
