I mean, it was funny eleven years ago, and he even managed to poke fun at himself when he was on SNL the first time, by playing up his temper tantrums and meltdowns . . . it's like he acknowledged his problem, and showed he could have a laugh at his own expense . . . it was even funny for a few years after that, what with, "I'ma let you finish" becoming memeworthy and all.
But . . . after so many years, it's just stopped being funny - intentionally or unintentionally - and has just become sad and pathetic. Like Trump, he clearly has issues, but he won't sort them out.
