Why is English so weird?

Why do we say 'I climbed' not 'I clomb'? Why is there a 'p' in 'receipt' and not in 'deceit'? Why is 'of' spelled with a 'f' when it sounds like a 'v'?

Michael Rosen hears why from American linguist Arika Okrent. Together they talk about the strangeness of English and who is to blame for the mess.
