I have autism so I have a tendency to do or say unusually things without thinking.
I bumped into a man with massive amounts of ginger hair and and a large ginger beard, in the pub, he said hi and I responded with 'you have hair like Aslan, I love it' and walked away.
At church I met someone twice in one day and when he greeted me the second time with a high five I complied but with the comment 'I've already met you today'. Why I thought that was appropriate I have no idea luckily the guy knows me well and is used to autistic people and the lack of verbal restraint and just laughed and joked about it.
My friend and I were wrestling over a toy spring (we're both in our 20's so why we were fighting over it I don't know, most likely boredom), ended up with me straddling him while still wrestling, other friends walked into the room at that exact moment, one yelled what are you doing and the other went purple yelled we'll just leave you two alone then and backed out quickly 
. My mother was nearby and we just got a look from her conveying do what you want but not on the couch 
and no amount of talking to any of them will convince them there was nothing going on other than the fact that my friend and I are children and wrestling over toy spring.
Another time walking through a theme park I knocked the same friend as befores backside with my backpack as I was swinging it to put it on. Something another friend saw happen yet he will not be swayed from the fact that I smacked his backside
Same friend growled in my ear while we and other friends were playing a boardgame (at a church event), making me jump, make a squeaking noise and turn purple and respond with 'you shouldn't growl at me outside of the bedroom' 
Which broke him and our other friends and I have no idea why I said. I and my friends are all very Christian and virgins and I've never been alone with this friend in a bedroom so why that was the first thing that jumped out of my mouth I have no idea.
The same friend decided that it would be a good idea to blow in my ear while we were all at the pub as group a friend asked what we were doing and I responded with 'he likes blowing me'. I have never seen men get quite so red, laugh so much or choke so quickly, problem was I had no idea what I'd said till he told me through his laughter, and I don't think I have ever gone so red.
I chastised the same friend in a French airport for jumping in front of another friend in the queue with 'your british, you know how to queue, you should know better' right in front of the security guard who needed to take five because he was laughing.
One that is not me but a friend. She got flustered when the guy she likes was wearing a shirt rather than cartoon t-shirts he normally wears and came out with 'You look good wearing a shirt, not that you don't look good when your not. I mean you look good wearing t-shirts not topless. I mean you do look good topless but .... You look good in shirts you should wear them more often'. Which I'm still teasing her about because I'm a good friend.
The guy that my friend above was talking to when meeting her dad for the first time was drinking milk and eating biscuits, which is fine, got confused and almost squashed a chewed/slightly soggy (think of what happens when a toddler eats biscuits) biscuit into her dads hand when he went to shake his hand.
Same guy when referring to the shop CEX (I pronounce it C as in Cat, he pronounces it as C as in Circle) said the phrase I had no idea Cex was so good. Which made my friend who fancies him laugh so much she cried. He went a funny colour and looked like he was debating laughing, hiding or sighing at our immature response.
