Why did comedian Paddy McGuinness clean Emile Heskey’s boots?

‘Take me Out’ presenter Paddy McGuinness was forced to do some boot cleaning after making rash promises before Bolton’s match on December 26.
Veteran England striker Emily Heskey is not known as a prolific goalscorer, and signed to the Championship club on a short-term deal just before Christmas.
He was expected to come off the bench during their game against Blackburn, but Bolton fan McGuinness was not expecting much from the 36-year-old.
If @EmileHeskeyUK comes off the bench today and scores for us I'll personally clean his boots! C'mon Bolton!!!! pic.twitter.com/337PJmBV8w

Of course, after saying that the comedian had virtually guaranteed the outcome and Heskey came off the bench and scored in the second half.
Fair play to McGuinness - he was true to his word and showed up armed and ready to scrub.
There you go, a man of my word. @EmileHeskeyUK boots, spotless!!! pic.twitter.com/5ZpSn7OHV5
