While looking for a Simpsons Wall clock for my son I came across this:
Talking Simpsons wall clock:
3 phrases - Doh, Gees, Buuuurrrp
3D Moulded effect on clock face
Chimes on the hour with phrase
Requires 4 x AA batteries
Currys only offer this online not instore pick up but the postage is only £2.99 & you also get 5% off with currys discount code.
Also 5% with Quido too - don't forget.
I think it's the cheapest "decent" simpsons talking wall clock.
