Most embarrassing moment with a parent

I'm just curious as to what embarrassing moments you've shared with a parent. My worst was probably after I came out and my dad was showing me some music download site he had found and as he clicked the search bar a LONG list of gay porn came up of what I had searched in the past (even though I frequently deleted my download history etc). We shared a long stare and he said well at least he came out to me before hand else he'd be shocked and quickly moved the conversation onwards and showed me how to deleted things properly.
