Scream, Scrame

My youngest son was telling me about a scary dream he had. At the horrifying climax, he said with wide eyes, "I scrame as loud as I could!"
Now that makes sense in an English-exception rules way..."come-came, scream-scrame."
This made me wonder all over again about the English Language. How can we ever even communicate? I found a fun answer it Steven Fry's presentation. Check it out! Kinectic Typography
