They Say of the Acropolis... -- if you haven't seen this, you really should. Ahh, improv.

My childhood speech impediment included difficulty saying the letter 'L' in some cases. I loathe listening to certain recordings of myself, because I really sound stupid. It never really did go away (I flatly refused speech therapy). But now that I'm an adult, every now and then people on the phones will ask me if I'm from Europe. I don't know what flavour of English accent Scroobius Pip has, but I hear the same shape to the letter when he says it.
