Being a wheelchair user myself I found this sign both hilarious and sad:
Some funny snapshots of signs from the USA...
And my favourite one from this lot is:
At the Travel Agency:
"Go Away"
In the Camping Shop:
"Now is the summer of our discount tents"
At the Clairvoyants:
"Closed due to unforseen circumstances"
In an airplane toilet:
"Smoking in the lavatories is prohibited. Any person caught smoking in the lavatories will be asked to leave the plane immediately"
At the Vet:
"Back in five minutes. Sit... Stay!"
At the gynaecologist's:
"Dr. Jones, at your cervix"
At the plastic surgery:
"We can help you pick your nose!"
At the optitcians:
"If you don't see what you're looking for, you've come to the right place."
On a maternity room door:
"Push. Push. Push."
In front of a funeral directors:
"Drive carefully. We'll wait."
In the non-smoking area of a restaurant (before the ban):
"If we see smoke, we will assume you are on fire and take the appropriate action."
Outside an exhaust centre:
"No appointment necessary. We hear you coming."
On the side of a plumber's van:
"We repair what your husband fixed."
On another plumber's van:
"Don't sleep with a drip. Call your plumber."
On an electrician's van:
"Let us remove your shorts."
