It's already happened....
The youth of olde England scoff up so much fast food with their fingers that the dexterous use of knife and fork is a long forgotten skill.
Teenagers cannot adequately fork their peas.
It's a wonder they could successfully stab anything harder than a Sponge Bob square pants.
Um. Given that the fork goes in the left hand, shouldn't that be sinistrous (sinister) use of fork?
