Unknown Tongues--Tomfoolery or Not? (n.d.)
Morris ChalfantChurch of the Nazarene
A number of people in the Bible "speak in tongues;" however, the Bible never claims that "speaking in tongues" is incontrovertible evidence of God's presence in the speaker. In fact, it can also signal demonic possession. Therefore, "unknown tongues" may well be "tomfoolery" and should be treated as such.
I did a little extra research and discovered that "Tomfoolery" is a word that dates to 1812. No one seems to know the exact derivation, but I'd like to think there was once a guy named Tom who was very easy to fool by resorting to obstreperous comic shenanigans.
