It’s such a great sketch, the whole speech of the “small” Ronnie is based on words starting with H, except when the “large” Ronnie is holding his breath :)) (sketch is still out there on the Internet, but in horrible video quality)
“H-hay fever? H-hay fever, absolutely h-horrid, h-horrid! I suffered from it on h-holiday once in H-helensburgh, yes, I was h-hibernating in the h-hotel the entire h-holiday!” (The Two Ronnies show, Garlic Breath sketch)
Stanks a lot, Amelia :))
