In another clip, one news presenter points out how Khan contradicts himself while making political statements - something that the United States president has also been accused of time and again.
Meanwhile, Imran Khan will take oath as Prime Minister at a ceremony at Aiwan-e-Sadr in Islamabad Saturday morning.
Khan's victory represents an end to decades of rotating leadership between the PML-N and the Pakistan Peoples Party (PPP), punctuated by periods of military rule.
The army and Mr Khan's party deny any collusion.
In Friday's lower house vote, Khan garnered 176 votes to defeat Shehbaz Sharif from the outgoing Pakistan Muslim League-Nawaz (PML-N) party, who won 96 votes.
PTI candidates were also voted Speaker and Deputy Speaker of the National Assembly this week, putting Khan in a strong position to carry forward his legislative agenda.
Most pressing will be a looming economic crisis, with speculation that Pakistan will have to seek a bailout from the International Monetary Fund.
In his victory speech following the polls, Khan said he welcomed any investigations, and that his party would support the process. "You had said that if rigging in 2013 elections would be proven, Nawaz Sharif's government should resign".
Cricketer-turned-politician Imran Khan was elected Pakistan's 22nd Prime Minister by the country's National Assembly on Friday, three weeks after his Pakistan Tehreek-e-Insaf (PTI) party won the highest number of seats in the general election.
Khan shot back that he had "struggled 22 years" to become premier. He said, "I am going to Pakistan as a goodwill ambassador". "No military dictator raised me".
How Mr Khan addresses historic civil-military tensions that have dogged successive governments could define his term, analysts say.
A sharp increase in oil prices - Pakistan imports about 80 percent of oil needs - has contributed to a current account deficit that widened by 43 percent to $18 billion in the fiscal year that ended June 30.
