Rylan said the "F" Word ?

The other night as Randy was heading down the hallway and Andrew said from his chair, that Rylan just said the "F" word ! Randy was like
"what", OMG the "F" word, how could he learn that word... we don't even use that word...and the only other vocabulary he has so far is saying Dada, Dat and a occasional Mama, so why would the "F" word be next....

Turns out the "F" word was a fart LOL ..So we are thinking that all this time Andrew has thought that "Fart" saying it, or doing it, is the "F" word...
