Oh man, I've been looking for this one for ages!! Easily my favorite SITBC skit! "You never call, you never write, you never call saying you're gonna write about calling...!"
Hi Mom? Yeah I'm just calling you to give you a heads up about the letter I'm going to send. It's going to read "Dear Mom and Dad, how's it going? Good I hope? Miss you two so much, but I'm doing fine here. I'm going to call you guys Saturday at 5 PM. Can't wait to hear from you! Love Jimmy" So yeah, expect that letter in the mail some time. Hope you get it, and hope you write me back, bye!
