Deeb slow rolling Matusow is one of my favorites also - it's hysterical when players such as Matusow and Helmuth who are frequently rude start lecturing others when it comes to poker etiquette.
However, my real favorites are when slow rolls backfire and there are a few classics on You Tube....both of these win with the same card on the river...
The first is from an Irish Poker Open when a German player Andreas, slow rolls Donnacha
O'Dea who is regarded as a poker icon in Ireland...it does not go well...

My all time favorite is at the Aussie Millions when some complete tool, Habb, attempts to slow roll Samantha Abernathy. In fact he angles when he makes his initial bet then starts acting like a drama queen as the hand plays out. He get his ass handed back to him on the river...and the fact Jason Somerville is commentating and cheering for Samantha Abernathy really makes the clip...
