Airplane - which features classic one liners such as 'I am serious and don't call me Shirley' - came out top in research conducted by a panel of members of movie subscription service Lovefilm.

They calculated the precise number of 'laughs a minute' for the top 10 comedies chosen by Lovefilm members.

The panel recorded the total number of times each film generated a laugh, before dividing it by the films' total length in minutes to calculate the precise 'laugh a minute' rating for each movie.

With a 'laugh A minute' score of three, Airplane beat nine rival comedies to top the list which has been created to mark The Hangover becoming available to stream on Lovefilm Instant.

The Las Vegas man-movie featuring the bachelor party to end all bachelor parties marked its arrival onto the Lovefilm Instant service by scoring a 'Laugh A Minute' rating of 2.4.
