I've got a couple, although mine are nowhere near as outrageous as some I've heard of.
One was 'Bridge Man'. He was really short and spent an hour (possibly more as I may have nodded off) talking about bridges.
Anther was a guy I met for coffee who, as soon I walked in, I knew we wouldn't be suited. Anyway, I was already sat down facing forwards, he sat in his chair, leaning back, legs crossed but the main thing was he never once made eye contact. Plus he only talked about himself.
Oh and, the other was when he suggested going for a drink. We went for a walk first (how romantic I thought) then he produced 1 can of Fanta for us to share. That was our drink 
Thankfully, I have a lovely DP now so no more of this malarkey but love to hear all the tales. I did OLD for years!
