Houseguest (1995)

Synopsis
Sinbad offers some unusual advice on how to make friends in this wacky comedy. Kevin Frankin (Sinbad) is a guy who dreams of starting his own business. However, getting it off the ground is another matter altogether, and soon Kevin discovers that the two loan sharks who fronted him money want to be paid, and paid promptly, otherwise Kevin will be spending some time in the hospital. On the run through an airport, Kevin is trying to find a way out when he overhears Gary Young (Phil Hartman) wondering where his friend is. It seems that Gary has arranged a reunion with an old friend from childhood, but since he hasn't seen him in 25 years, he has no idea what he looks like today, beyond the fact that he's black. Kevin fits the bill that far and claims to be Gary's long lost buddy, which Gary buys hook, line, and sinker. Gary seems to enjoy bonding with his old friend, and Kevin likes staying at Gary's fine home (and raiding his large icebox), but Kevin discovers that impersonating a stranger is a lot more complicated than he expected after he's forced to perform oral surgery and give a speech at a grade school "Career Day" presentation. However, this is all small potatoes on the "oh, no" scale when the loan sharks track Kevin back to Gary's home in the suburbs. ~ Mark Deming, All Movie Guide
