Not exactly world famous but me and my mate were in the same pub as ob from hollyoaks in london one night, being completely wrecked we kept asking him where max was, why are you not with max, is max coming out later on, endless inane questions about max.
I think initially it was vaguely funny and he took it in good humour but it quickly got old and yet we still continued mentioning it every time we saw him which in itself is pretty funny.
