I get it all the time!
When my dodgy left hip, right knee, and knackered foot are all playing up at the same time, I've been told many times that I walk like I've shat myself!
And you know what, I agree, I do walk like I've shat myself sometimes, when all those injuries flare up all at once, but I find it funny, and I have a bloody good laugh at myself with them, even though these injuries are a real blight on my life, I can still have a laugh about it.
Not everyone is a snowflake, who can't handle a bit of banter and P**s taking you know, most have their heads screwed on enough to see the humour in things, no matter what it is.
