Just days after suffering a heart attack during a live performance last week, Gallagher told us he's having financial issues and needs to raise some cash in a hurry ... or else.
Among the items Gallagher is hoping to sell -- a set of giant bowling pins, an oversized tricycle, a bike contraption, tons of weird contraptions ... and a 1989 Mercedes ... but he can't find the key.
As far as his health is concerned ... the 64-year old comedy legend tells us he's feeling "fine" after doctors placed a stent in his heart -- and is excited to get back onstage so he can smash more stuff.
Check out the video to see some of the awesome stuff he's selling!
