I can sometimes fart on command, iin?

I've posed enough weird stuff and asking weird questions on this site. but there's sometimes when I am sitting, i stand up for a second and sit down and all of a sudden, an actual fart seems to pop out of my butt. i can do that a few times before it stops. the thing is, before it does occur, i don't even have the need to fart. strange or nah?
