Luke's lobotomy is a 3 object pattern invented by Luke Burrage.
The siteswap is (4x,2)*, with outside 4s and active 2s. Each 4 is thrown with a hand crossed over the other arm, and caught in the same position in the other hand. Each 2 is thrown under the arm, and then the arms uncross and recross the other way, and the 2 is caught in the same hand, crossed over the other arm.

504 Mills mess with the 4s thrown under the arm is an asynchronous pattern very similar to Luke's lobotomy, and the time-reverse of that pattern is similar to Jay's jumble.
