When I was on the 360 bus the other day, I noticed that the recorded
message said Pel-ham Street, as in Pel-[green eggs and]ham. I have
always (of course!) said it like pellum; but perhaps TfL "knows
something".

There is a bus stop in West Ealing which used to be "The Leedo"
but has now been re-recorded to "The Lydo". (I don't know how to
pronounce "lido" myself, to be honest)
