Yes, I do it's "Hooray! Thank you for rescuing me. My name is Yoshi. On my way to rescue my friends, Bowser trapped me in that egg." from Super Mario World. He doesn't say much in the series but that's one of my favorite quotes from him. I liked his special message in Super Mario 64 as well. Of course I also like "Yoshi!" from plenty of games.
I just remembered, his quote "I'm the kindest there ever was!" from Mario Party 3 is tied with the Super Mario World one.
