I don't see the letters 'lol' all together as a stand-alone phrase anywhere in there. Instead, I went for the more mature and non-homosexual single 'hah', as opposed to the more frivolous yet still non-homosexual double 'hah', as in 'hah hah'. Most times I go for the understated yet quite effective 'heh', but this time I was a bit more amused than usual.
