Jack Vale is a Youtube comedian/prankster who is a family man (married with 5 kids) and fellow Christian. His material is basically PG family fare, and his specialty is "Pooter" (a flatulence device he invented) videos in which he uses said device in stores and various other public places to pretend to "poot" near random people. He does other pranks, as well; he also has a family vlog channel (those seem to be popular) where he vlogs the fun things that he and his family do together. They are very tight-knit, and the love they have for one another shows.
I also realize that there are some Christians who have problems with "fart humor". I am not one of those people, however. People have different convictions and should respect one another despite that. I know some here might disagree (and to those who do, please do so respectfully), but I see passing gas as one of many quirks/imperfections of the human body, and to joke about that is no different than joking about pimples, "bad hair days", chattering teeth, goosebumps, eyes that widen when frightened, sneezing, the way different people laugh (some snort, some wheeze, some squeal, etcetera), mannerisms, and other things that naturally amuse some people when it comes to the human body. It amuses me, too. There's just something about the various sounds. Nothing dirty about that... except maybe the odor that follows!
Here is one of the more recent "Pooter" vids for anyone who may be interested.
For those who don't do "fart humor", Jack has other videos, too.
