YouTube user Retrontario frequently uploads fantastic retro-Toronto-centric gems. These clips never fail to bring back a ton of memories for me, so I feature them from time to time.
I'm sharing this Geocel Caulking ad because it includes one of the most unintentionally hilarious lines in Toronto advertising history. Perhaps you could get away with saying it's "completely different from other caulks" back in 1984, but I doubt it.
For additional giggles, there's a rebate at Beaver Home Centres.
