Yes, although I can believe that you weren't intentionally mocking God.
Humour is fine such as Christchan and the jokes this board, and is a great way to connect with people and dissolve prejudices against Christianity but I don't think it should involve immitating Jesus. It isn't very funny, gives the impression that you don't experience God as a person, and doesn't command respect for the faith.
Imagine what you'd think if a Muslim started immitating Muhammad. Its a type of self-deprecating humour that's embarrassing behaviour for the devout.
