In the opening for Conker's Bad Fur Day, Conker uses a chainsaw to cut up the Nintendo 64 logo in half, then shoves it aside with the chainsaw while saying "Stupid logo!", then throws the chainsaw away and takes out a Rareware logo.
During the Rare Xbox Commercial now owning the rights to Rare, Conker was seen using the chainsaw to carve the XBOX logo to spell out "rare". When he met Kameo, Conker tossed the chainsaw aside as it inflicted pain upon Banjo, due to falling in love.
Toward the end of the Project Spark trailer, Conker appears out of nowhere and cuts the title in half, then jumps up and says, "I couldn't resist." Then, the blue orb of light puts the title back together. Unlike the previous two sequences, Conker doesn't toss the chainsaw aside.
