Who remembers Bing Crosby Boxing on the XBox? See if this jogs your memory.

Get ready for the fight of your life as you take control of one of the meanest, middle-of-the-road mothers ever to don a pair of gloves. Yes, Bing's in the ring and it's up to you to guide him along his path to glory as he takes on a legion of legendary crooners, including Sammy Davis Jnr, Dean Martin and Bobby Darin.

Want to send Englebert Humperdink spinning into the ropes? Want to grind Frank Sinatra's face into the canvas? Or maybe you just want to see Doris Day spitting teeth? Well, an all new game engine and detail-texture-mapping bollocks means that Bing Crosby Boxing will be the most authentic, bone-crunching slugfest you will ever experience. Honest.

singers in the mouth"

Available for X-Box, PS2 and that Nintendo thing. You can probably get it on the Gameboy as well, I don't know, try Woolworth's or somewhere like that.
