For those just joining us, our friends The Human Giant are hosting a 24 hour marathon on MTV to raise awareness for their website.

Every hour we are giving them a phrase to say on the air. So far they are 2 for 2! The last hour's secret phrase was "Cat Boner" and they delivered.

This hour (4pm eastern) they need to say "That'll tickle your umbilical cord." Submitted by David at UNLV.

Tune in to MTV to see if they make it happen.

The next one will be the last, so leave your comments/suggestions below for the 5pm secret phrase!
