Ed usually had some funny recollections of his father if you remember the series. I remember a similar bit like this that went something like:

Ed: Sarah will tell Mom, and Mom will tell Dad, and Dad will say "Not now, I just got home from work."

And another one that went something like:

Edd: Oh, my. A shriek of terror.

Ed: Dad's home!

This sounds eerily similar to how my dad would respond.
