"Intelligence officials say they had a hard time predicting Russia's invasion because Vladimir Putin doesn't own a cellphone or use the Internet due to fear of being tracked. You can tell Putin doesn't spend much time online. When he says 'LOL,' he means 'Look out, Latvia.'"

 –Jimmy Fallon

"That's right, Putin doesn't have a cellphone. 

And just like everyone else without a cellphone, 

he won't stop bragging about it."

 –Jimmy Fallon
