Would an accidental one be where you fart, and then like half an hour later you kick out from under the covers and it attacks like an IED? Then In that case, yes on the accidental, though I do like getting the wife with those too. I go to bed, she goes to the bathroom to do her nightly face scrub, I fart under the covers, she comes in, all naked and stuff, flips the covers back to hop in bed and BAM I laugh everytime.......... .......especially when she goes, "You coulda fuckin warned me asshole"
