Danny "Gift" Garcia and Keith "Run Time" Thurman are both clever reversals on their actual nicknames. Quitali Quitschko is also funny based on the fact that it makes no pretence at being subtle or clever at all.
David "Hamster Lungs" Price is a quality nick name. Not do much a hating name as pointing out an obvious weakness.
