Ugly Christmas Sweaters Canada - Christmas Coffee Mug | RetroFestive.ca "UGLY MUG party. Head over to the Dollar Store or search your cupboards for the ugliest mug you can find. We'll have extra mugs if you can't find one. Come for "mug-sized" drinks, treats, & games! There will also be a white elephant gift exchange w/ a $5 cap. If you don't want to participate, that's fine. Party w/ us anyway."
